VLC's avi muxer is broken, and nobody wants to fix it, since avi apperantly
is a horrible format. Try mp4 or ogg, these muxers are much better
maintained. You could also try the ts muxer, but I seriously doubt anything
but vlc would play the result.

Most probably. If you can write a encoder module for vlc, you can probably
search through the ogg muxer for the fourcc as well? Probably a real easy
fix. If this makes your xvid module useable I guess we should consider
including it as a light weight alternative to ffmpeg.
