I have a couple of CD's (our of a few thousand) that my G4 PB (1.5/17) and my external CDRW won't read. In fact neither drive will mount either of these discs. They both play fine on any other CD player I can find and neither is labled with any copy protection. Any ideas? One has Quicktime and other media on the disc - is that the problem? Can I get my PB to think more like a PC? I want to get these b*stards into iTunes.
