Odd.  Avidemux supports multiple sound track.

What does this mean?  You aren't using avidemux to re-encode the video
are you?

You should know that "-dumpaudio" doesn't work properly with AVI files
because it adds extra bytes to the output.  This has been discussed
over and over on this mailing list.

In general, you can't keep them in sync.  Using CBR audio and "-vf
harddup" will give you better odds, though...

Well, you can use EDL with mencoder for editing.

Well, I would suggest creating two AVI files with identical video, but
different audio tracks.  Make all the edits on one of them with
avidemux, and when you're done, you can save the edit list, or
project file (or whatever they call it this week) and apply that to
both files.  Once that's done, you could merge those files with
mkvmerge, but tell it not to copy the video stream from one of the two
AVIs.

I've never tried it, but that's where I would start...  Actually, I
would start with avidumex's dual audio stream support, but you said
that didn't work for you for some reason.
