Concerning Copy Control Signals

TV broadcasts that contain copy control signals may have one of the
following three signal types, COPY-Free, Copy-Once and Copy-Never. If
you want to record a copy-once type program, use a DVD-RW disc with
CPRM in VR Mode. You can also use DVD-RAM discs.

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 recorders, 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.
During playback, the ID is read from the BCA and used to generate a key to
decrypt the contents of the disc. If the contents of the disc are copied to other
media, the ID will be absent or wrong and the data will not be decryptable.
