Looks like mplex is failing to re-mux the video and audio streams back 
together because the audio stream is corrupted. If you go to 
mytharchives settings pages on the second page make sure 'Use FIFO' is 
unchecked and re-run mytharchive with the same file. This time it will 
complete the mplex stage before running dvdauthor. Should prove that it 
is mplex that is failing. What source is the file from - does it have 
the audio already in ac3 format or has the ac3 audio been re-encode from 
an mp2 audio stream? Is the audio stream playable? It should be located 
in /video/archive/work/1/stream0.ac3.
