OT: extracting audio from DVD

[Filippos Klironomos]

Hello, 
 this is slightly OT but since people here have been using 'xine' or
'mplayer' long enough they might help by pointing to the right
direction. So my problem is I want to extract the audio (music but not
dialogs if possible) from a DVD as a typical audio file or files that
I can then burn to a CD.

If someone has done that it would be greatly appreciated if he/she
shares the knowledge! I am pretty sure it has to be a simple 'xine' or
'mplayer' command...

Thanks!
F.

P.S. In case you are curious what DVD I am talking about it's 'The
Fiddler on the Roof' which has amazing 'soundrack' (if you can call it
like that since it is a musical to begin with).
