Hi,
I have a DivX file with a stereo audio stream, and an external AC3 stream for the same DivX file. I want to eliminate the stereo stream (wich came with the video) and replace it with the multichannel stream. I'm trying to use Nandub to do it, but I'm having problems with the sync. I've played with the preload and interleave options, but it seems that I'm far from understanting clearly how these parameters work. The strangest thing is that the delay is not constant, the movie starts fine but the audio seem to go a little faster than the video and it keeps getting worse as the frames passes. I've used AC3Fix to detect problems with the AC3 stream, but none was found.
Anyone knows what can I do to solve this?

Thx,
Gustavo
