Spawn??? Probably isn't the type of thing I'd rip. I can't address the possibility that the cd includes some particularly nasty DRM, but, assuming that's not the problem ...
Do you know how to rip it in Windows? The theory is the same, and it should take roughly the same length of time. I, personally use the program, Grip, but there are several others that work just as well.
Do a forum search for something like 'rip' (Advanced search, Titles only might help you search.)
