In cases to transcode DV I use -x xml for kino's smil lists and somtimes (mostly $EVIL_OS codecs) -x mplayer is the only solution.

AFAIK you can use some external sound editor to change the sound if in need. IIRC it has to be frame accurate (1/25sec). Only did this once to get menu sound for a dvd I authored myself and it both took some time and it is some month/years ago. -- bye maik
