Mpeg Sync Problem

[no_reason]

Here's the problem, I'm trying to convert a divx to mpeg and when I try to open the movie it doesn't let me open the sound! So I go in VDub and extract the sound to a wav and convert it. The problem is that the sound is out of sync, I can sort of tell when it happens a few times because it either a) stops for a few seconds or b)replays the sound that just occured. When I checked the individual wav it had no skips at all. Also another point is when I open the movie in VirtualDub and try and play it, it says: "The requested audio compression is not compatible with the input format. Check that the sampling rate and channel count of the input match those of the requested format" Also when I open the movie it has the error of improper VBR audio stream. But the thing is... I DID extract it to wav! Anyone willing to help me, because I'm much to lazy to edit out every little jitter in goldwave...

First of all, if it is simply VBR encoded MP3, the simple solution is to open the avi file in goldwave and save it out as a wav from there. This usually fixes the problem. However, the other error message suggests the possibility that the sound is Ac3. Open the avi in virtualdub and check what it says under file->file information. If it has 5 channels then it is 5.1 Ac3. There are guides and loads of info in the forumson converting this to wav. If it says 2 chan but under compression it says something like tag unknown it could be 2-chan AC3. Use gspot to confirm this. Again, same kind of thing applies, convert to wav like 5 chan Ac3, then encode.

Hope this helps.

Okay, the sound is a 2-chan tag unknown... But how would I convert it to a 5chan AC3 wav?

You can't, well not properly. Use Headac3he to convert it to wav.
