Default 256.29: Jerky VDPAU HD playback in MythTV

Driver betas 256.29 and 256.25 both exhibit jerky playback of 1080i ATSC streams in MythTV here. This is with a fanless GT-240 card that plays the exact same clips smoothly with 195.36.24. 64-bit all around.

It could be an issue with excessive use of the CPU (not GPU), as we've noticed it while MythTV is simultaneously recording HD while playing back HD. It seems less noticeable when only playback is active.

FWIW, 256.29 is slightly better than 256.25, but neither is great.

Back to 195.36.24 again for now.
