Audio out of sync just in the middle

[Lobelto]

I captured an .avi file 53 minutes long. It is in-sync at the beginning, gets out of sync in the middle (lips start moving and sound follows 3 to 4 seconds later) and gets in-sync again at the end. Has anybody encountered this before? Are there any programs that will warp the audio by setting multiple sync points, not just at the beginning and end.

Thanks

Where do you notice the sync problem? On the computer when viewing the AVI, or when it is burned out to a DVD?

Just curious, because if it is the latter (when burned out to a DVD), it might be because of the player itself... I've seen odd problems where one player will play the video (stuff I captured, edited, and authored) just fine, but another player will go in and out of sync with the same video.
