Unrecordable video

Video with copy protection cannot be recorded on this DVD Recorder.

When the DVD Recorder receives a copy guard signal while recording, recording stops and the following message appears on the screen.

You cannot record copy protected movie.

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 programme, use DVD-RW with CPRM

in VR Mode and DVD-RAM.

Media	Signal type	Copy-Free	Copy	-Once	Copy-Never
DVD-RW(Ver.1.1)		O				-	-
DVD-RW(Ver.1.1)
with CPRM
VR mode		O			O	*	-
Video mode		O					-
DVD-R		O					-
DVD-RAM(Ver.2.0)		O			O	*	-

Once “Copy Once” has been recorded, recording cannot be done anymore.

-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. 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.
