Ceton PCI intermittent problem: NO TV SIGNAL


So I have the Ceton PCI card and all is well and good.  But every few days, I get the pop-up box saying:

There was no TV signal on channel 44 so "{show name}" could not be recorded.  Reschedule the recording after verifying the TV signal is working for that channel.

However, when I go to Recorded TV, that very show is indeed recording.  Any ideas what's causing this pop-up to occur even though there's no real issue?

Any info appreciated.

I have an Infinitv usb tuner and have seen the same thing a couple of times.

I'm getting that too, i have the usb version.  I don't know what to do.

i have had this issue as well, i am on comcast and I have 2 OTA HD channels (ABC and NBC) no longer works so i am using the SD channels.  I have not had time to trouble shoot it.


I have updated the firmware with 0 fix.


I am wondering if something was changed on the cable side?


what provider are you guys using?

Hi Jon,

Do you have tuning adapters?  You can see this error with tuning adapters (generally Cisco's)  take too long to tune request a channel.  If so, what happens is:

1- Media Center attempts to record on Tuner X.

2- The tuning adapter takes too long to respond

3- Media Center does not see a signal on Tuner X soon enough so it reports failure

4- Media Center attempts to record on Tuner Y

5- The channel was already allocated in step #2 so the tune request responds quickly

6- Everything records properly but has the failed message from Tuner X

Note: Lots of steps left out (i.e. oversimplified)

I see the same thing occur on occasion, but the program always seems to record with no problem.  I don't have tuning adapters and it happens on my Hauppauge 2250's as well as my Cetons.  I'm thinking that if WMC can't get a lock on a channel using one tuner it rotates between available tuners until the channel comes in.  It's not unusual to get several failure messages in a row for a given program. 

I think that WMC just has too tight of a window between the time it looks for a channel and the time it declares a fault.  Perhaps there's a registry hack to extend the time window before the fault is declared.  Either that or maybe the selected tuner can be checked X number of times for a signal lock before the fault is declared.

I see this with my Ceton4 too.  Same thing -- warnings, sometimes several in a row, but ultimately the program records just fine.

A reg hack to adjust the timeout would be nice, but I'm not aware of one.

Or... Ceton could just make things tune a little quicker!   Come to think of it, I don't recall this problem happening with the earlier Ceton firmware -- I think it was an update drivers/firmware (this spring) that started causing it.
