Ok. So is it possible to concatenate 2 vob's where the audio and video 
don't have the same stream numbers ?

Do I need to change the container ? If so, what container would work ?

For instance, what should be the filename extension in this script ?

for input in *.VOB ; do
   ffmpeg -i $input -c copy  $(basename $input .VOB).[???]
   echo $(basename $input .VOB).[???] >> concat.txt
ffmpeg -f concat -i concat.txt ..........    out.mp4

Bigger question : is the concatenation problem here the stream numbers ?
