    stole “numerous ‘pre-release’ DVDs and Blu-rays” between February 2021 and March 2022. He then allegedly “ripped” the movies, "bypassing encryption that prevents unauthorized copying

    How? Especially pre-release bluray?

        No, i mean, bluray DRM is partly bound to keys and the player. Even blurays from 2020 often fail with libbluray and a newish player. I see no way to rip a pre-release bluray.

        DVD is a bit more tame with only CSS and no BD+ VM on the drive.

        For Details, look here.

            With libredrive flashed on your player. Let the player decrypt for you, and then copy the decrypted stream, no need to break any encryption…

              I wish it wasn’t so ungodly difficult to flash a drive in Linux. Proper documentation would be nice too. I do have a flashed drive however.

          I’ve never ripped BluRays but from what I’ve been told by someone who is apart of a P2P release group the jist is there’s an exploit in Intel SGX that made BluRay protection obsolete and the tools to crack BRs are practically publicly available if you search around for a bit. The funny thing is newer CPUs/mobos don’t support Intel SGX, which is one way to stop it.
