What is CPRM?

DVD

CPRM is an acronym for "Content Protection for Recordable Media". It is a type of copyright protection technology, a system that allows recording only once. Specifically, you first record a program and dub it to a CPRM-compatible DVD. Up to this point, there is no problem. However, if you try to further copy this CPRM-enabled DVD, the VRO extension in the DVD will be protected by CPRM. It will not be playable on ordinary media players. In this way, the copyright will be protected.

If your computer's DVD software does not support CPRM, the copy control signal will prevent playback. In this case, an error message such as "Disc not compatible with playback software" will appear and you should not be able to play it.
