A most disquieting and inexplicable problem: I recently purchased a CD (independent artist). However, when I put it into my MBP's drive, it gets spit back out again. I haven't had this problem with any other discs (either audio CD, data CD, DVD movie or data DVD). I'm at a complete loss as to why this happens. Also, the CD is read just fine by my Dell laptop. So, I suppose it isn't a problem with the CD? Help, anyone?
