Josh, after thinking about it
Josh, after thinking about it for a little bit, I’m starting to not want any extenders for the way I use my media. The primary benefit of an extender is that I won’t have any copy protection issues from the WMC HTPC. However, if my current cable company (Charter) has all standard TV as copy freely and only the premium channels as copy once, a secondary small WMC HTPC (that pulls the content from the primary) in the bedroom would be more powerful as it won’t have all the issues that extenders have.
A drawback to having multiple WMC HTPC’s would be that the Ceton doesn’t support tuner pooling (that I know of), so maybe another tuner setup would be better. This just opens up a new questions that should be in their own thread.
