Audio Sync Issues

[Pinata]

I've recently been ripping some of my DVDs using DVD Decrypter and encoding them to xvid using autogk and all has mostly been well. At first I had out of sync issues with a few, due to using VBR, but I was able to fix these in virtualdub and encoded the rest in CBR. However, Apocalypto was encoded using CBR, but it is still out of sync. Stranger even, when I open it in virtualdub, it seems to be in sync, but is out of sync if I play it in VLC/Media Player/Media Player Classic. It seems to be a constant delay. What is up with this and what can I do to remedy it?

Try rip with latest dvdfab decrypter instead and see if you notice any difference.
