Why can’t I copy or move the video from a DVD recording a digital broadcast to another DVD?

29 October 2021

Digital broadcasting (terrestrial, BS, CS) can be recorded only on CPRM compatible DVDs, but the same data does not remain on multiple recording media, including hard disks.
Also, after recording to a DVD, you cannot digitally copy or move from that DVD to another recording medium.
The mechanism is to protect the copyright holder with the copyright protection technology called CPRM.
