The quick thing to try is to make sure XvMc is turned off - with setup, 
you don't need it.

The path on the frontend menu, the path is:

Setup->TV Settings->Playback

On the first screen of options, there is one for "Preferred MPEG2 
decoder" - make sure that is set to standard.

You do have the proprietary Nvidia driver installed, don't you?  Check 
your Xorg.0.log file for mentions of loading module 'nvidia' instead of 
driver 'nv'.  The open source nv driver does not perform nearly as well 
for video.

Beyond that, do what Brad suggested - try to capture from the tuner card 
outside of mythtv, and playback the file using something like mplayer, 
VLC or xine.
