Using trunk won't fix the restarts. There caused by glitches in the
video or audio. Personally I think it has more to do with glitches in
the 5.1 audio rather than the video.
I had a lot less problems before 5.1 audio support was added.
It might help with the recordings not playing back. I am running trunk
and don't have any problems playing the recordings.
The problem isn't with Mythtv it's the firmware are the driver and are
crappy cable or satellite companies.
