Can't a Blu-ray's playback be disabled by revoking the AACS cert (or whatever key) the blue-ray uses for DRM in the blu-ray players? Especially since they're all always connected now.

LibreDrive firmware + Makemkv for the win

  Interesting. Hadn't heard of LibreDrive before. For anyone else wondering, this seems like a good explanation: https://forum.makemkv.com/forum/viewtopic.php?t=18856 https://forum.makemkv.com/forum/viewtopic.php?t=18856

    Yeah, the wording around it is a little confusing, but the tl;dr on it is you use their firmware flashing tool to overwrite the existing firmware on your Blu-ray/dvd/UHD drive if it's compatible. Then there are no more restrictions on what your drive can read whatsoever. Region locks, DRM, etc all go away.

Unless you're using the Blu-Ray player for something else, there's not really a need to connect them to the network. Maybe to ease firmware updates if you want those. Yes, some discs have something that does something with the network, but I can't imagine it's worthwhile (but maybe if I knew what it was, it could be?) One of my blu-ray players had a bunch of streaming clients, but they pretty much all expired. It might be nice if you could use a blu-ray player to play discs copied to your network, but I think DRM makes that a no, and anyway, 4k blu-ray can exceed 100mbps at peaks, and I don't think 1g ethernet has made it to 4k blu-ray players yet. But it has for some models of Apple TV, and some android TV products, including the well regarded Nvidia Shield.

  It can happen even without connecting to the network. The discs that new movies are on can have updates that will disable your player's ability to watch any DRM'd Blu-rays, even old ones that previously worked in it.

I never connect my 4k region free blu ray player to a network. Don't see how the certs being pulled will matter.

  If a drive that fully implements the AACS spec opens a disk with a newer version of the MKB block, the drive will update its flash and refuse to downgrade to an older MKB block. If the software you are using to talk with the drive had its host certificate revoked in the newly update MKB, the drive will refuse to work with that software forever. A active network connection isn't required.

    This is insane. The disk is a Trojan horse.

      It's been the same way with video game consoles for years.
