The sync problem is a long-standing one, and this method has been tried. It may work sometimes, but I strongly doubt this is the final word.

Has never worked for me. I've found that the only cure is using a different video player (highly recogmend mplayer) and making sure that you have a fairly fast computer depending on the video size.

Maybe you should just try a video player that plays movies correctly. Try vlc and mplayer.

For out of sync movies use 'Sync-Hole'
http://nsorscher.home.comcast.net/apps/Sync.html
This program attempts to sync your quicktime movies by changing the framerate of sections of the video track(s), or changing the offset of the audio track, and it works great! It only save a move with dependencies, so once the audio is synced the way you want it then open the movie with dependencies in quicktime and then 'save as' a standalone movie and the movie you save will be in sync.
Hi. I am the author of Sync Hole and I was just googling my page because I've recently moved and had to change my comcast identity.
The new url: http://nasorscher.home.comcast.net/apps/Sync.html
also a more permanent mirror:

And one more thing, you can set it to make stand-alone movies in the preferences, which I guess nobody ever looks at.
And really one more thing, if you do go the Add Scaled route, whatever you do make sure you add the VIDEO scaled to the AUDIO, not vice versa. Scaling the audio changes the pitch and also the sample-rate, which means that the cpu must resample on the fly back to a rate supported by the sound card in hardware. This will increase playback requirements of the movie and also often causes 'soft sync' problems where the sync gradually gets worse, but pausing/resuming fixes it (which doesn't sound so bad, but if you think about it it means the sync problem can never be fixed for that movie)

I would also point out that Sync Hole often doesn't work when I first open up an AVI file. Instead of showing the movie, it's a blank screen. To make it work when it does this, go to file/add movie to get the movie to show up. Then you can fiddle with the A/V settings.
Another tip, make tiny adjustments. I always start between .25 and .5 seconds as adjustments. It's almost always somewhere in that range that makes the movie perfect.
Good luck!

3. Click on the video track, click on the 'extract' button
4. Click on the audio track, click on the 'extract' button
5a. If the video lags the audio, delete some small time (start with .25 if it's minor) from the beginning of the new video only movie; delete the same amount of time from end the audio only movie
or
5b. If the audio lags the video, delete some small time (start with .25 if it's minor) from the beginning of the new audio only movie; delete the same amount of time from end the video only movie
6. Select all the audio, copy it
7. Activate the video movie, choose 'Add to Movie' from the 'Edit' menu
