Last night my dad was watching Hitch on his system and I pointed out that it looked like it had been dubbed in. The voices just didn't match up with the picture but only by a little bit. It looked like you saw the video first and the audio slightly after that. I found out that it wasn't just that dvd because I tried a DVD that I made where all the transitions are matched perfectly to the music and all of them were off.
