Yes of course. Thanks for the tip. Extracting with mkvextract and then
mencoder -ovc copy -oac lavc produces a working avi. There's a problem
with the video, though. mplayer plays it fine, but my standalone DVD
player doesn't. I've run into this with some other xvid videos as well.

I know "packed bitstream" or "vop packed" as avidemux calls it can cause
problems, but removing that doesn't seem to help in these cases. Could it
be quarter pixels, perhaps? Can they be removed without reencoding? Or 
what would be the least damaging lavcopts for reencoding the video?
