One of the ways the audio and the video can get out of sync is because the video is fed directly to the screen while the audio is routed through a home theater receiver (or the equivalent), for example. Better HTR's may have audio delay circuitry the user can invoke to try re-sync the two. I have not had personal experience with noticeable delays in my setup. Note also that the d**n cable boxes and the cablecos themselves are not immune from blame on these matters either.
