Downloaded XviD & "asynchronous blit" out of s

[DRP]

I'm sure many people have experienced this before. You download an XviD file of something and it looks for all the world just like every other XviD you've ever downloaded. It plays perfectly on the computer with whatever media player you choose to use but then when you go to convert it, the audio ends up being massively out of sync right from the get go. Specifically the audio is > 1 sec too early.

Then you look at it a bit closer and you start to notice the other telltale signs that all is not as normal as it first appeared. When you play the file on the computer there is a huge delay before the audio track starts; When you change the framerate header in the AVI to 25 for PAL conversion you find that you can't change it back to 23.976 again (closest it will go is 23.975).

I've done some reading and some think this has to do with something called an 'asynchronous blit'. Where can I find out what that is and how it pertains to these particularly annoying XviD files? I want to try to find a solution to converting these extremely difficult to convert files.

At the moment, converting involves trying to guesstimate the audio delay and then reproducing that in the output somehow, which is not very exact.

A lot of problems with downloaded XviD/DivX files stem from VBR MP3 audio.

What does GSpot tell you about the audio ?
