And have you ever seen any pressed disc DVD with this flag? As I said, I have never encountered a disc which indicated CPPM or CPRM. I assume if I had, it would have not played on one or the other of my drives but I am still not sure if CPRM being checked is good or bad. Also, just because CPRM is checked does that mean anything in relation to CPPM?

Sorry to be so obtuse, but I just have never seen this protection related in any way to pressed DVDs in any source.
