[mythtv] XvMC issues with a digital channel supplying a lo-def feed, but not with a HD feed.

[Dave Just]

I have this issue with XvMC and recent svns, but I don't have hdtv.   
Sometimes an MPEG2 stream will work okay, other times it will have  
intermittent crackly audio and/or hang after a few seconds of  
display.  With the standard decoder there is no problem.  (I'm using  
NVidia driver 7667 on a GeForce 4 MX).
