I think you have interlace sync issues. If you are running MythTv with 25Hz output frame rate the 50Hz fields can be either in sync or out of
sync. When there is motion in the picture all is smooth when the fields
are in sync. If they go out of sync you will ge a lot of motion jitter.
If you are able to set "Bob" de-interlacing, this may fix the issue for
I am using Bob already. I'm pretty sure it's just that the timing is around the frame display interval, so any jitter directly translates into showing a frame or missing it.
I don't see this with mplayer or Xine and have manually gone through the code, but I can't see why we are getting jitter on the timing which is worse than the xine case. I have stuck in a bunch of timing stuff and redone my Jack audio output for sub microsecond jitter timing accuracy, but I can't quite shake it. Very annoying actually
The sleep() timing method is better for me, but still has problems occasionally.
