I think I have some confusion about the Media Code and what it represents.
I am currently under the assumption that there exists on each and every blank DVD made in the world a globally unique identifier for that particular disc. And that this identifier is etched into the burst cutting area and can be used by CPRM to protect copyrighted material. Is this true?
What I seem to be finding out is that not all discs have this identifier, and even if they did, not all DVD writers can read it. If such an identifier does exist, does anyone know of a list of DVD writers that can read it?
Thanks so much.
