| Thanks Erik,
This is a somewhat disconcerting issue. I have not noticed the problem on my 40" Samsung LCD, but then the low quality of the Quicktime movies I generally get from the picture department often makes it very difficult to determine absolute sync by eye, especially when the security watermark is right in the center of the screen.
For feature films the whole sync issue is iffy anyway. The distance from the screen to the mixing position in a large dub stage can result in as much as 3/4 frame delay in the sound. A dozen or so rows of seats in a theater would constitute somewhere around a frame of delay, so much of the audience in a large theater is hearing the audio anywhere from one to two frames out of sync. I noticed this even as a small child because my Mom was late to everything, so we always ended up sitting in the very back of the balcony of the large movie palaces they had back then, which means the sound was probably close to 3 frames delayed. Everything looked like a Kung Fu movie.
This is no excuse not to get the sync correct, although ever since the advent of digital picture and sound editing, I have never been absolutely confident of dialog sync anway.
