Blog - Niveus Media Discontinues Consumer High End Media Center PC Systems

If Ferrari stopped manufacturing sports cars, would that mean that cars in general are dead? That's the question posed to me today as I learned from confirmed sources that Niveus Media--the creators of arguably the most luxurious high end media center PC's you could imagine--has announced to their dealers that they will be discontinuing manufacturing of all of their consumer lines of Media Center systems. Instead Niveus (now rebranded and removed the Media from their name) will be turning their attention towards specialized software opportunites, such as Project Snowbird which will enable secure streaming and file transfer of premium content from copy protected service providers. Niveus manufacturing will continue on a modified scale now focused on volume digital signage opportunities.


I have been assured that Niveus is not going anywhere as this transition was made due to the increased software demands and the desire to ensure that they aren't competing with their potential PC OEM customers who are also selling media center systems on a larger scale. From my understanding of the present CEDIA channel, less than expected sales probably had an influence as well. Existing customers will still receive the same support and warranty as promised upon purchase.

So where does that leave Media Center? On the heels of all the positive announcements from IDF regarding Windows 7 Embedded, I think this is just a small step towards a more streamlined Media Center PC. Gone are the days of the power hungry Denali's as the demand for something smaller, quieter, cooler and more affordable have taken over. For now, if you want to see more about what Niveus is up to, head over to their new website at .

Blog - Crap, it's not always Comcast

Let me start with a disclaimer, this does not pertain directly to home theaters, it is a simple lesson in my own humility.  And when it comes to technology, I very much dislike feeling stupid.  Read on if still interested, otherwise check out some of the new reviews.

Blog - Shutoff your HTPC when not in use!

These features have been widely available in Mythtv since at least 2008 but in the last couple weeks I have finally been able to implement ACPI shutdown/wakeup for my Mythtv server.  Using the information found here I have setup my backend to power off when not recording a show.  The system automatically sets the time of the next recording and will wake up 5 minutes before hand.  Also, if there is a show starting within the next 90 minutes it will not shut itself off.  Otherwise, the system will automatically turn itself off after 20 minutes of idleness.  All of the specific time values are user-definable and can be set to whatever you want.  I've had my setup running this way now for about 3 weeks and it has been flawless for me (other than the one time that the BIOS hiccupped when detecting hardware and prevented a proper boot sequence).

There are still a couple of areas that I need to improve.  I would like to set the system to suspend instead of shutdown and I need to set the frontend systems to wake the backend when starting up.  I'm sure that I'll be tweaking the various time settings for a little while too, but I am very happy with this setup right now.

If you haven't already done something similar in your HTPC software you should definitely consider looking into it.  What started me down this path?  I looked at last month's electric bill.  I've been meaning to do it anyway but that was enough to push me along.

Good luck and leave a comment with your experiences if you decide to do this with your system.

Blog - Mythtv for Windows

I am happy to say that I now possess two Windows based laptops that each have the Mythtv frontend software built natively on them.  The Mythtv devs have been very busy over the lasts couple of weeks putting together a server to host all of the Mythtv dependencies - MinGW, MSYS, etc - so that the build script will reliably build for Windows users.  You are no longer forced to see if there is an updated package when the build script is unable to find the version that it was expecting.  I can say from experience with both this script and the previous versions that this one is much easier to use.  The process is still the same but you save a lot of time and headache not hunting down the dependencies.

Blog - Getting your Ceton InfiniTV 4 this week? Some hints to a successful install...


First, let me start off with an apology.  I've been burning the midnight oil but still have some tests left for Part II of my Ceton InfiniTV 4 review.  It is getting there and if you do have any questions, please ask.

With the delay in Part II and consequently Part III I wanted to share some hopefully helpful hints for a successful install.

Blog - I bought a new HDTV...and it's not 3D

8/10 UPDATE:
The unit arrived this morning! Absolutely beautiful. Haven't had a chance to play with it much yet, but thought I would share the picture!


A bit of a history lesson--I have been putting off buying a new HDTV for quite some time. When I first moved to the bay area about 4-5 years ago, I bought a used 32" Westinghouse 720p LCD television, knowing that I would be moving several times and only having it in my bedroom. Shortly after, I got a job working for a home theater company which loaned me a 40" Vidikron for me to test with, 1080p of course, so that also helped with the postponement of my own purchase. That TV was in the living room and the good ol' Westinghouse went in the bedroom. Long story short, that job ended, the TV was returned and I was stuck back to my 32" in my main living room at a lower 720p resolution. The resolution downgrade actually didn't affect me as much as dropping a mere 8" from 40" back to 32".

I decided to have a conversation with our resident AV Expert Andrew Van Til, the very proud owner of a Panasonic VT25 3D 1080p HDTV television set, who once again encouraged me to purchase a new TV to "properly test and evaluate for MissingRemote." This would come to be the most expensive instant messenger conversation of my life, as that was a good enough sales pitch for me...and thus the hunt for the right TV began!

Let me establish my own guidelines I setup before doing any actual research:

  1. I did not want to spend over $1000 -- I know I will move at some point within the next few years since I'm a renter, so not worth a bigger investment to me; plus I knew at that price I could get a pretty awesome set that compared to either Vidikron or Westinghouse which are both older models would blow it away.
  2. No 3D --  This is a combination of factors. Price as noted above was going to make it difficult to budget and get 3D technology, and if the TV hit my price WITH 3D, it probably wasn't going to be a high quality set. The main reasons however are that I would have little use for it, seeing as I only subscribe to basic I would essentially be paying the extra cost for the few Blu-rays I *might* rent that would be in 3D. I know the future can hold blah blah, but that's where budgeting only $1000 comes into play. If 3D takes over the world in 3-5 years, I can graduate this one and be able to justify buying a new one with 3D THEN.
  3. No frills/extras needed -- I rent an apartment, so wall mounting was OUT so it must have a stand. But as far as any technical extras go, I don't need Netflix, Yahoo or any other crazy pointless widgets these TV companies are coming up with these days--that's why I use an HTPC!
  4. 24p Not required -- This heavily would hit up against my #1 point, as it's a very expensive feature, and I just don't feel I would notice the difference enough to justify the price hit. Also since I'm running an Intel HTPC, I would have to deal with some issues there as well with handling the automatic rate switching.
  5. Tuner not necessary -- obviously since I have everything going through my HTPC, all my content goes through that including television tuning.
I was hoping to make this a quick blog...but it's not :-) So click Continue reading to read the rest!

Blog - Update: HD PVR for Windows Media Center

Minor update, Hauppauge added another registry key so the version being released will be 1.0.28190. The only change is that the FlushOnChannelChange registry was split into two settings, FlushOnChannelChange and PauseOnChannelChange.

We were lucky enough to get early access to a forthcoming updated beta driver, 1.0.28188, from Hauppauge for their HD PVR support for Windows Media Center. Normally we would update our original Preview: HD PVR for Windows Media Center and leave a comment or two about what was new—that would not do it justice.


So what is new?  Honestly not much.  Before you question my sanity let me explain. The currently available beta driver, 1.0.28171, is fairly stable and works as intended. For those that are already using the beta, there simply isn't much to add.

What they did add is huge for those hesitant to try the beta, in particular they have 1- added support for external blaster applications; 2- added the ability to toggle whether channel changing stops the encoder and flushes the internal queues or not to.

I am a 64-bit fanboy, but for those using 32-bit versions of Windows 7 this means you can continue using firewire channel changing via Tim M. Moore's FireSTB or any command line based channel changing method you currently use with DVBLink.

For those sticking with the internal HD PVR blaster, you can optionally choose to continuing using it in addition to an external blaster application.  This can help troubleshoot any channel changing issues that may occur by logging channel change requests.

For existing beta users there are a couple of fixes and new options.  The most prominent being the ability to toggle whether channel changing stops the encoder and flushes the internal queues or not to.  What does this mean?  By default the drivers will stop encoding when changing channels, this can cause a delay in Windows Media Center and consequently the dreaded low signal error.  You now have the option to turn that off. 

On a negative note, the external blaster application is currently only available via manually editing the various registry settings.  If that isn't improved by the public release I will provide an easy tool to configure the various settings.

There are a few other settings available so I urge you to read the upcoming release notes in detail.  If you have any questions please let me know.

A big kudos to the Hauppauge team working on the HD PVR for Windows Media Center support.  It is clear that they are listening to feedback and making progress towards an official Windows Media Center driver.


I've gotten the OK from Hauppauge to share the change log.  Please note that it is subject to change.

1.0.28190 Change Log

- Include latest WHQL’d HDPVR analog driver. 

- Include latest IR support for compatibility with other Hauppauge products. 

- Added “Blaster” registry key 




And several values to control blaster operation (defaults shown): 


• "ActiveBlaster"=dword:00000001  

0 - no blaster 

1 - use HDPVR blaster 

2 - launch external blaster application 


Used to select the active blaster.  This is a bitwise value so multiple bits can be set.  

When set to “external” the application specified by "ExtAppName" will be launched with 

the command line parameters specified by "ExtAppArgs". 


• "FlushOnChannelChange"=dword:00000001 

0 - internal queues are not flushed after blasting 

1 - flush internal queues after blasting


• "PauseOnChannelChange"=dword:00000001 

0 - encoder is not paused before blasting 

1 - pause encoder before blasting 


• "IntOpenMode"=dword:00000000 

 0 – internal blaster port is opened once and handle saved for subsequent use. 

 1 – internal blaster port is opened/closed on each use


Opening the blaster once provides faster operation but the saved handle will be 

invalidated if any other application accesses the blaster hardware. Once the handle is 

invalid the MCE software will not be able to blast. For example, if you test the blaster 

operation using BlastCfg.exe you must reboot the PC (or restart the service) or the 

blaster will fail when MCE next tries to change the channel. 


• "ExtAppName"="D:\MyTests\blast.exe" 

Used to specify the full path and name of an external blaster application.  External blaster 

mode must be enabled in "ActiveBlaster" for the application to be executed.  Do not 

include opening and closing quotes in the value you specify. 


• "ExtAppArgs"="-c%c" 

Use to specify the command line parameters passed to the application specified in 

"ExtAppName".  The MCE software will replace the first occurrence of %c in the 

command line with the channel number to be blasted.

Blog - Sage My Movies Preview

PluckyHD has done some amazing things with SageTV, the most popular being Sage Movie Wall.  Instead of converting the wall for Sage V7, he's been working on a port of MyMovies for Sage V7 conveniently called Sage MyMovies (SMM).  The private beta has been running for a couple months now and what he has accomplished not only gives V7 users a fantastic replacement for the stock video library but also highlights what the new animation and rendering system in V7 is capable of. 

Now SMM isn't quite ready for a public beta (probably not until the end of July), but Plucky has decided it's time to share some screen shots and a video that will give all the Sagies out there something to look forward to.

Blog - What's happening?

It seems that it's been a while since I last updated my blog. At that time I was looking at running the various Mythtv-based linux distrobutions.  Among the distrobutions that I had mentioned are Mythdora, Mythbuntu and LinHES.  At the time, I had tested Mythdora. Well, I recently found myself with a bit of free time so I decided to load up Mythbuntu 10.04.  I have to say that if you're new to Linux and want to take Mythtv for a test drive, it doesn't get much easier.  It was litterally a matter of answering a couple of questions during installation to determine which pieces you want installed (frontend, backend, etc) and then a regular Mythtv configuration from there.

Looking at these newer distrobutions made me start thinking about upgrading my production Mythtv network.  It is currently running version 0.21 and Mythtv is up to 0.23.  So this got me thinking, what distrobution would be best for a dedicated Mythtv backend?  The reason that I'm in this situation is because my current system is based on Fedora Core 8.  Mythtv was installed from packages provided by  Unfortunately, this repository only supports the three most recent versions of Fedora and Redhat.  Fedora is now up to 13, with Fedora 14 coming soon I'm sure.  This means that in order to get support for my current Mythtv setup I would first have to update the OS from Fedora 8 to Fedora 13.  With a major jump like this I just know that I'm asking for trouble. 

One option would be to backup the Mythtv database, wipe the system clean and start with a fresh installation of Fedora 13.  However, I don't want to find myself in this situation again in a couple of years.  So I thought that I would throw this out to the community: What Linux distrobution would you recommend for a backend system?  I'd like to be able to keep Mythtv up-to-date without having to update the OS itself every six months or so.  Whenever I do an upgrade it inevitebly causes something to break, which brings down WAF for a couple of days. 

So what should I do?  Leave a comment!

Blog - What Do You Want to See Turned Into a Movie?

As a consequence of George’s [Skirge] well deserved ridicule in this week’s Blu-ray Releases thread, I realized I was a sucker for epics and I am guessing George is as well (*cough* Waterworld *cough*).  You may further mock me for leaping from Waterworld and Dances with Wolves to timeless classics such as The Battle of Algiers, Lawrence of Arabia, Spartacus, Ben-Hur and Braveheart but I did just that.  While reminiscing, my mind wandered to thoughts of what other epic films I would like to see made.

I realize everyone’s definition of what entails an “epic” film will vary but here is my list.

  • Snow Crash, by Neal Stephenson
  • Imajica, by Clive Barker
  • Stranger in a Strange Land, by Robert A. Heinlein
  • God of War, video game series
  • The Stars My Destination, by Alfred Bester (no Jumper was not good enough)
  • Ender's Game, by Orson Scott Card
  • The Dark Tower Saga, by Stephen King (broken into at least 3-4 movies)

What book, video game, comic book, graphic novel, cartoon, etc do you want to see turned into a movie?

Blog - Comcast Flubs ESPN3D Rollout

I love soccer – watching, playing even coaching is fun most of the time :).  So when Comcast announced that they would be carrying ESPN 3D in time for the World Cup I was very excited.  But even though ESPN 3D went live on Friday June 11th for South Africa v. Mexico I still haven’t watched a game.

Blog - HTPC Client Woes

Recently, my normally rock-solid HTPC client has been locking up and turning off every so often.  I had been thinking it was a memory issue and swapping some of the chips out and/or putting them in different slots seemed to make it work again.  This, in spite of the fact that memtest showed no issues at all.  I was beginning to think the slots themselves might be bad in the motherobard.  However, it's still happening.  Now, I'm beginning to suspect a failing PSU, so I'm looking for some options.  That Enermax reviewed earlier this week by SPCR sounded ideal, but it's simply not available here in the states.

I'm currently thinking about the Seasonic X-650 due to the modular cables and SPCR's glowing review .  I definitely want quiet, efficient, and modular.  650W sounds like overkill, but it's my understanding that you generally want to run a PSU at about 50-60% of its capacity.  A 450-500W unit would be ideal for my HTPC, it would seem that, based on the chart on this page , the Seasonic is my best bet.  Any other suggestions?  I'm also trying to find a decent price ($160 seems the going rate at reputable stores).  Newegg isn't usually an option for me because of shipping and sales tax.

Blog - Heatwave HTPC fun!

I've been happily chugging along with my SageTV server /client setup for some time now.  After 2 major snowstorms here in the northeast, accumulating a very unusual 48+ inches, only to be followed shortly thereafter by 2 rainstorms, which wound up with FEMA assistance coming in to some areas, we are now coming to the end of our first--quite early in the season--heatwave this week.  Monday started off in the low to mid 70's, ramping all the way up to nearly 90 yesterday.

Normally, this heat would be very welcome at this point, but it managed to bring about an issue in my SageTV setup.  It would seem that one of my HD-PVRs is having heat-related issues.  I have two of them side-by-side and only one was acting up around 10pm last night.  I had to reboot every time because it was a hard lock.  SageTV threw up a recording error in the middle of the show we were watching, so I immediately knew something was up.  The other HD-PVR was recording fine through all of this.

Luckily, I purchased a spare HD-PVR when I was initially having issues getting them working and was able to swap them out quite easily.  I set the backup HD-PVR to record something for the next hour and it did so without any issue whatsoever.  Given the heat we're due to have again today, I'll be watching this very closely to see if the backup has any issues.  If not, it's RMA time!

Blog - Vacation Update

Hey guys.  Here's a little tidbit that I thought I should share.  I was at Sea World yesterday with the family and while we were waiting to get on one of the rides in the kids play area the ride attendant directed that we "secure all cameras, video cameras, cell phones and Ipads."  I don't think that this is part of the official script yet but still...  It's been what, four days since they were made available?

Blog - Vacation time

Hello to everyone from California.  This week my family is on vacation in California.  Yesterday we thought it would be fun to take the little tyke to Disneyland.  She loved it.  So did I.  But the reason that I'm writing this post is because while we were there we went to the Innoventions exhibit in the Tomorrowland section.  It looks like they recently updated the facility because they had Media Center systems all over the place.  Everywhere you looked was another Media Center PC or a Control4 wall panel or a digital photo frame in one size or another.  It was all based on HP equipment - touch screens, monitors, printers, etc, etc.  There were a bunch of Xbox360s and lots of other displays like that. 

The other thing that caught my attention there was the Microsoft Surface.  If you aren't aware of what it is, it's a multitouch input/display device.  It is able to track as many fingers as you want to use.  This is the first time that I've seen one of these in person although I've been following the technology for a number of years.  In fact, it has interested my so much in recent weeks that I've started collecting pieces to build my own over the last two months.  So although it will probably take a few months to build it up, keep your eyes on the website here because I plan to blog about my build process.  When it's all done I intend to do a guide that you guys can all follow if you find yourself interested and want to build one for yourself.

That's all I've got for now folks.  Back to the warm sun.

Blog - Kudos to Monoprice

I've been a huge fan of as a company, due to their fantastic products and prices, for a long time now.  I now have another reason to love this company.  Recently, Monoprice was notified of a potential security breach when a few of their customers notified them "that information from credit cards they used on the Monoprice website had been misused".  While they had no indication that a breach had happened, nor any proof from customers that something was awry, they chose to stop taking orders entirely, notify all their customers of the situation via their website, and contacted numerous 3rd parties to conduct an investigation on their system.

According to Monoprice, as of 3/25, no security breach has yet been found, however, they have made numerous changes to their systems:

We rebuilt our network using new hardware and software. We reviewed all web application source code and all databases to ensure there are no security holes. Our network security is professionally managed. We have deployed an improved firewall. We're performing vulnerability scans using service provided by two vendors, Trustwave and McAfee Secure.


Additionally, we've contracted with a Qualified Security Assessor, Accudata, which is assisting us complete the formal steps to become a certified Level 1 PCI DSS merchant. Accudata staff told us the certification process may take several weeks.

Blog - Another Nail in the Coffin for Media Center?

Over the last year we Media Center enthusiasts have slowly seen Media Center, piece by piece, slip away. Last year at CES we saw the rise and fall of the Dish Network Media Center tuners. We saw Linksys discontinue their V2 Extenders , with the likes of Dlink and HP following suite right after. Last week at the Electronic House Expo (EHX) it was announced that the Media Center Integrator Alliance was abandoned. The Media Center Integrator Alliance website no longer exists, while Microsoft's own custom installer landing page is re-directing the custom installers to enthusiasts forums like The Green Button.

{joomsay link= [My Network Project]}The other bit of interesting news is that the Media Center Integrator Alliance has been dissolved. This group was formed about a year and half ago I think to really push Media Center in the custom integrator channel and provide custom integrators with exclusive training, tools and educational resources. The website is already down and custom integrators are being pushed over to the Green Button. Microsoft is still hosting a Custom Integrator landing page for Media Center but it links out to other sites such as the Green Button.{/joomsay}

I've come to realize one thing in the world of HTPCs, Media Center, and the likes will always be a niche product and will never become main stream. This news is just one more proverbial nail in the coffin when it comes to making Media Center main stream. If custom integrators can not get behind it then how can the average Joe get behind a product that custom high end installers are not even using?

While I do not see Media Center going anywhere any time soon, with the advent of the Ceton cable card tuner and the plethora of innovative third party plugins being developed by the community, and innovative new hardware solutions , I just don't see it being enough to sustain the future development of Media Center.

Have any thoughts? Leave a comment and discuss.

Blog - ATI Digital CableCard Tuners End of Life?

ati-tv-wonder.jpgIf you have been following the CableCard tuner for Windows Media Center PC's news recently, you have seen announcements from two vendors--SiliconDust and Ceton--who are developing their own M-cards (multi-stream) CableCard tuners which will enable access to premium content on multiple tuners with only a single CableCard.

What has been missing from news for quite some time, is where ATI is in all this buzz. For history, ATI produced the first (and still only) Digital CableCard Tuner (DCT) back in early 2007. For quite some time, those tuners were only able to be used via a few select OEMs which went through the process of being authorized to do so, as ordered by Cable Labs. That first generation product suffered from a plethora of bugs and instabilities which eventually led the larger OEMs like Dell to stop selling them altogether.

After many requests--and even a hack to bypass the OEM restriction--Microsoft was finally able to remove the OEM restriction and open up the CableCard tuners to all users with the release of Windows 7 (Vista users are still SOL). Great news, but then it became clear that ATI’s DCT were becoming increasingly harder to find. News of the Ceton and SiliconDust tuners is great, but still those are not expected until late May at the EARLIEST. So this would seem like the perfect opportunity for ATI to capitalize on, right?

Well, the reason they haven't is probably one you have suspected (I sure have) by now--ATI is getting out of the game, and maybe tuners in general. A source inside AMD/ATI has revealed to me that the CableCard tuner (and possibly all other tuners) is EOL, meaning End of Life. When a product hits EOL status, that means no more are being produced, and they will be available only until current inventory sells through.

I was unable to discover just how long the tuners have been EOL. Are the available tuners ones that have been floating around the distribution channels for years now? It also isn't even clear when the most recent shipment was. Either way, once they're gone--which they are already hard to find--they will be gone for good. And along with this, don't expect another firmware update (although in fairness the recent one fixed a ton).

I think what saddens me about this is the way ATI was treated. They suffered through all the early growing pains and were rewarded with ridiculously low sales for their tuners, which I'm sure cost a fortune to develop since they were the first. The restrictions to who could use their products, combined with the awful reputation they garnered I'm sure made the EOL decision that much easier. While everyone involved should shoulder some blame, no doubt it was ATI who took the biggest hit with inventory which probably took them years to run through. Given the news, you have to wonder if they even sold through their original stock.

Blog - A look at Solid State Drives (SSD) v. Hard Drives (HD)

Like rocket cars, moon vacations and watchable online video we all know that solid-state drives (SSD) are the future.  Of course it will be a long time before any of us can afford to replace that 2TB drive with one, but with prices for smaller SSD finally approaching a reasonable level it makes sense to start thinking about how to fit one into the HTPC (especially a client).

Blog - Upgrading to the Harmony 890

As my wife and I planned the new layout of our TV room (which I know I still need to post about), I quickly realized that I would need to replace my Harmony 880 with an RF remote.  Due to cost constraints, I couldn't go with my Christmas wish of the Universal Remote MX-880 and settled for the Harmony 890, which is simply an RF version of the 880.  This upgrade was fairly painless, except for the screwups I brought upon myself.  What I can tell you right away is that the 890 is just as good as the 880 and the RF aspect works fantastic!  The rest of this update is posted with my HTPC Client Blog, so head on over to read and see the rest of this upgrade.

Blog - Simple Blu-ray Playback with SageTV, SageMC and Total Media Theatre 3

Sometimes I forget how much I love SageTV, SageMC, and TMT 3. This forgetfulness usually occurs when I have started tweaking things but not found enough time to set things up properly. I had experimented with various methods to launch Blu-ray playback on an old SageTV install before I moved to Windows 7. I had gotten ripped BR folders to play on my HD200, and discs to playback on my full client. However my method of setting this up wasn't the most straight forward. Sometimes things are easier than we make them.

Tonight everything changed. I took a look at SageMC's External Player capabiliites. Suddenly eveything fell into place. In less then ten minutes I had my SageTV launching TMT 3 for playing back both ripped Blu-ray folders and discs. If you have SageTV, SageMC, and TMT just follow these simple steps.

Edit the following file in C:\Program Files\SageTV\SageTV\STVs\SageTV3\SageMC\

- dvd_player.cmd : Replace existing text with this (including quotes, alter drive letter as necessary): "C:\Program Files\ArcSoft\TotalMedia Theatre 3\uMCEDVDPlayer.exe" %1

Save and Close the file. Then launch SageTV, goto SageMC Setup->External Programs, and then enable External DVD Player.

Ta da! Full support for Blu-ray folders and discs from SageTV on your HTPC. Only issue I seem to have is that when SageTV wakes back up the W7 menubar is on top of it. I'm pretty sure I can resolve that.

EDIT: Solved the problem with focus, used EventGhost to do a Bring to Front on SageTV.exe.

Blog - Is Bit streaming more efficient than LPCM?

The recent update to the Haali Media Splitter (enabling Dolby TrueHD in DTS-MA MKV) got me thinking about revisiting our guide to getting lossless audio off the PC.  When an interesting discussion got started about the benefits of bit streaming v. LPCM over at AVS Forum it was time to do some testing.

To setup the test I muxed TrueHD, DTS-MA and FLAC (converted from the TrueHD track using eac3to) tracks into separate mka files and played them back in GraphStudio using ffdshow for bit streaming TrueHD/DTS-MA and decoding TrueHD/FLAC and the ArcSoft Audio Decoder to decode the DTS-MA track (ffdshow can't decode DTS-MA yet) while tracking power usage and CPU utilization.  Check out the results below.


To be honest the results were somewhat surprising.  I had expected bit streaming to always be the most efficient way to push audio off the PC.  While we can see that it is marginally more efficient than real-time decoding TrueHD and DTS-MA during playback, at least when it comes to ffdshow and TrueHD converting to FLAC before muxing the MKV is the better option for CPU performance.

Given the numbers achieved bit streaming BD using PowerDVD and Total Media Theater on the platform (0-5%) and what ffdshow is capable of with DTS-MA I expect that there is some room for improvement, so we will have to revisit this topic again.

Blog - Is Bit streaming more efficient than LPCM?

The recent update to the Haali Media Splitter (enabling Dolby TrueHD in DTS-MA MKV) got me thinking about revisiting our guide to getting lossless audio off the PC.  When an interesting discussion got started about the benefits of bit streaming v. LPCM over at AVS Forum it was time to do some testing.

To setup the test I muxed TrueHD, DTS-MA and FLAC (converted from the TrueHD track using eac3to) tracks into separate mka files and played them back in GraphStudio using ffdshow for bit streaming TrueHD/DTS-MA and decoding TrueHD/FLAC and the ArcSoft Audio Decoder to decode the DTS-MA track (ffdshow can't decode DTS-MA yet) while tracking power usage and CPU utilization.  Check out the results below.
