Audio/Video slightly off .. can it be corrected?

Hi everybody ..

I'm new to your online and am hoping someone here can offer some advise on correcting a problem I'm having.

I downloaded a movie in .AVI format. The first 20 minutes or so of it are great in that the audio matches the video perfectly. But from that point on it becomes slightly off and within another 10 minutes the audio is off by a second or two.

Is it possible to somehow decompile the audio and video and then recompile it or is there some other method which correct this problem?

Thanks for any help!
