Re: copy protected audio cds with linux ?

I don't understand this. What is this "hidden signature", and how does
it prevent the disc from playing on a CD-ROM drive? If the disc is fully
Red Book-compliant, then why would it not play? Is this a cheap trick
like putting a faulty non-audio session on the disc (separate from the
Red Book CD audio data) in the hope that a CD-ROM drive would be
confused by it, and therefore be unable to read it?
