I have mythtv running on an Asrock Ion 3d, both frontend and backend. It 
works pretty well, watching live TV or a recording uses about 15% of the 
CPU in the front end using VDPAU. There is a problem how ever with audio 
sync, the picture trailing the sound by about 140ms, that I've never 
been able to work out a fix for. I am getting tired of setting the audio 
delay every time I watch a problem though.

I'm running Ubuntu and tried running 0.25 from the PPA however the VDPAU 
decoding didn't seem to work properly and wasn't able to play the video 
at anything more than a frame a couple of seconds.

Any suggestions on either of these problems?
