You can try to demux and mux the VOB files to get a proper MPEG2 program
stream which is compatible with dvdauthor.

Something like this:

  % cat *.vob | tcextract -a 1 -x ac3 -t vob > audio.ac3
  % cat *.vob | tcextract -x mpeg2 -t vob > video.m2v
  % mplex -f 8 -o av.mpg video.m2v audio.ac3

You can use FIFO's instead of the video.m2v and audio.ac3 files and 
start the processes in parallel for better performance. I attached a 
small (quick and dirty) shell script for this purpose. It grabs all 
*.vob files in the current working directory and remuxes them into a 
single .mpg file.

Pass filename, audio track number and codec as command line options:

  % cd /path/to/vob/files
  % remux-vob /tmp/test.mpg 0 ac3

Hope this helps,

Regards,

Jörn
