[mythtv] DVD playback issues, patch

[Johnny Stenback]

Hello David,

Thanks for digging in here. I haven't been able to test your patch on my 
primary system where I use VDPAU for playback yet, but I did test using 
software decoding and software rendering and it does not seem like your 
patch fixes the problem I'm seeing, and in a way it seems to make it 
worse :(

Without your patch, if I fast forward for just a second after starting 
DVD playback, the audio/video speeds sync up and remains in sync from 
then on, but with your patch I can't seem to get audio and video to ever 
be in sync, it's always off by what looks like ~2x.

I wish I could help more here, but I don't know this code at all and I'm 
unable to spend any serious time on this in the foreseeable future.
