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.
Disc contents cannot be copied to other media.
