Not existing audio track number specified

Hi,

I had a problem when I tried to rip a DVD-to-DVD copy that had only  
one audio track. After some checking I found out that the reason is  
that dvdrip specifies for the first audio track also the track number  
0: '-a 0'. Using tcscan on the ripped vob files showed track number  
1. Specifying '-a 1' as transcode parameter allowed me to use dvdrip  
to rip this dvd.

Is a single audio track DVD that doesn't specifiy track number 0 a  
DVD that doesn't follow the standards or should we try to use the  
tcscan output to get the right track numbers?

I had another DVD with a single audio track numbered 2. Also in this  
case tcscan showed the correct track number and specifying transcode  
option '-a 2' helped.

I always activate 2-pass option. Since the audio is not ripped during  
the first pass the problem occured AFTER finishing this pass. :-(

Do you have an idea how complicated it is it analyse tcscan output to  
determine the correct audio track numbers?

Regards

Michael
