When I try to burn a DVD with ImgBurn I get a message that the disc is copy protected:

Copyright protection system type: CSS/CPPM

I've been trying to Google on how this protection actually works, all I could find is that there's some secret sectors on the cd that are used for decryption of the data.

However I'm wondering - how is this enforced (someone has to "know" that those sectors should be read by the secret decryption key) - is this some sort of specification on the DVD drive? or perhaps some specification that the operating system "knows" about and therefor decrypts the data successfully?

After reading about it on the Wikipedia that user pjc50 posted in his comment, I understand that it's the drive that enforces the encryption.
