good question in the post above.
reclock can help you if you are watching the movie on the computer.
if it is the dvd player.. there needs to be an audio sync feature to adjust the audio to the video.
what devices does the video run through?
what devices does the audio run through?
if it is a hardware problem.. the hardware itself could be causing it because of the different things connected.
like.. if you have a receiver doing the audio.. maybe the receiver is slow.
or
maybe the television is really fast.
