I don't have any issues and both my FE's are AMD .. an opteron 170 (dual core)
and an opteron 146 (single core) One is using an 8600GT and the other is using an
8400GS...  both CPU's sit at 1000Mhz even during HD playback.

I did have this issue until I turned off an option that was recommended
(something being synced to opengl)..

I believe the settings you refer to are kindly noted at

The issue also occurs on mplayer, which are outside the mythtv settings, implying a problem outside mythtv.  The NVIDIA drivers seem 
the most likely place, given they have already purportedly twice fixed Display Pre-emption faults....
