content Protection for recordable Media (cPrM)

CPRM is a mechanism that ties a recording to the media on which it is recorded.
It is supported by some DVD Recorder, but not by many DVD players.
Each blank recordable DVD has a unique 64-bit media ID etched in the BCA(Burst Cutting Area).
When protected content is recorded onto the disc, it can be encrypted with a 56-bit C2 (Cryptomeria) cipher
derived from the media ID.
Disc contents cannot be copied to other media.
