Extracting from SVCD?

[Charles Martin]

Hi all:

I was wondering if anyone has a method for "ripping" an SVCD. I have 
just burned some music videos onto SVCD and now I'm wondering if I can 
ever get them back off of there if I were to want to make a new 
compilation at some point in the future.

The files on the SVCD disc are still MPEG-2, but they are substantially 
different (and unplayable through Quicktime) to the MPEG-2 files I 
mastered with, which play fine with QT Pro + MPEG-2 component.

I'd like to be able to delete the "source" MPEG-2 files after they are 
burned to SVCD, but at present I'm stumped on how to extract them back 
to "regular" MPEG-2.

Advice or URL pointers (bearing in mind that OS X solutions are 
preferred) are appreciated.
