I use Vegas and married up some audio to video that wasn't fitting right - the video was getting ahead of the audio and so I went in and edited out a single frame of video on an existing edit point {so you couldn't see any jump} about every 50 secs through the whole show concentrating where it was noticeably out of sync and it came out really good but it was tedious to do. You can work on a % of time stretch/shrink to apply but if your source was tape based to begin with it might vary during the course of the mpeg and there won't be one 'magic number' to adjust the whole piece.

good luck
