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 decrypting key) - is this some sort of specification on the dvd drive? or perhaps some specification that the operating system "knows" about and therfor decrypts the data successfully?

    en.wikipedia.org/wiki/Content_Scramble_System ! I remember the controversy when the decryption program was leaked, and its distribution is still legally questionable in many places. – pjc50 Dec 14 '18 at 10:02
  • @pjc50 - After reading that Wikipedia now I understand that the drive enforces the encryption. I just didn't manage to find the correct Wikipedia until you posted it.. so Please post it as an answer and I'll accept it. Thank you. – BornToCode Dec 16 '18 at 16:09

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.
