By jitter I refer to what appear to be dropped frames, slight skips in smooth motion during periods of high motion. Not the "Sound is freaking out" constant jitter or actual slow playback.
I've noticed this too, and I describe it almost as
"cogging" because the hiccup is very regular. For
example when a camera pans across a scene I see smooth
panning interrupted by regular jerks.
You might also check that your video refresh rate is very close to 59.94 (60 * 1000/1001) Hz (for US). If it's not, Myth will have to periodically extend or skip a frame to keep in sync.
If you're not running AC3 passthrough, you can instead try turning on "use video as timebase," which will warp the audio instead of the video. I am not sure if this was changed to use the new libmythsoundtouch stuff, or if it still audibly speeds up/slows down the audio.
One other thing to check... are some shows 29.97 / 59.94 Hz and some shows 30/60 Hz? I've read that networks plan to transition to 30/60 Hz once the analog NTSC stations are off the air; maybe some shows are being produced that way now? If so, Myth needs a way to select a video mode with the proper refresh rate added to its capability to pick one with the proper resolution.
