I want to create a bit-by-bit backup of my DVD and a Blu-ray disc without removing its encryption. Is dd be the best method, and if so, what flags or settings should I use? Also, is comparing the SHA-256 hash of the generated ISO file with the hash of the original disc’s raw data (read from /dev/sr0) the best method for verifying the backup’s integrity?
@Sxan@piefed.zip nailed the main point. I’m making a legal backup copy of the content to store on DVD/Blu-ray discs in case something goes wrong or the disk get corrupted
there is no legal issue with ripping your own dvd and using it on a jellyfin server or even making dvd copies.
the only restriction is you cant distribute or sell access to them
DVDs have been around long enough that they are going out of style.
How many people have been convicted of backing up their dvds?
So how ate to blwgalkt going to watch it? Legal players well not play it.
