[MacDV] help extracting audio from a dvd

[davi merelyn]

Hi,

I am trying to extract audio from a dvd with 2 parts, but I can only  
ever get 1 part.

To be able to get the audio, I take these steps.
1. Use either HandBrake or DVDxDV to get a file that I can edit in  
quick time.
2. I edit out the parts that I don't want, and import it into iMovie
3. I then extract the audio and import it into iTunes and burn a cd.

I can never get the 2 parts of the dvd ( which has been copied from a  
commercial dvd using MTR and then toast ) I have tried with about 8  
different dvds with 2 parts and I have the same problem. I don't  
necessarily get only part 1 some of the dvds give me part 2 only.
I have tried opening up the part that I don't get in dvd player,  
closing it, with the hope that because that part was playing last the  
copy might come from that part, but it doesn't I still get the same  
part as I got before I bothered doing that.

I hope this makes sense, I'm not good at explaining things, however if  
anyone out there has any suggestions or questions to ask to try to  
solve my problem I would appreciate it.

Many thanks
