There are ways to fix the sync, I just don't know what they are. Don't
give up hope. :)
Though...hm. One thing you might try is keeping the 'video' streams in
'copy' mode, but transcode the audio streams to something like 256kb/s
MP3. It'll increase your file size slightly, but the tools may be
clever enough to maintain sync better that way.
