I wish I could answer, but I don't even understand the question :-[     
(as it is painfully obvious, I am quite new to this multimedia stuff). 
The resulting file that is created by mplex has sound - it can be played 
in mplayer just fine. Does it have 1 audio track or two (and dvdauthor 
finds the silent one) - I don't know, and I have no idea how to check. 
But is sounds quite plausible - then my question becomes, how do I 
instruct dvdauthor to use the correct audio track, and not the silent one?

Carl, demux (which as I understand, is done by ProjectX, right?) 
produces two files - 1 video (*.m2v) and 1 audio (*.mpa). Are you saying 
that it should produce second audio file (*.mp2 maybe)?

Do I understand your question correctly? Does my question make sense?
