This is significant because any compromised host keys would be revoked. If that disc has a newer MKB version then what's on the drive, then your drive's firmware is updated with the new MKB. You go out and buy the latest XYZ movie on UHD.

To understand why I'll give you a scenario. Awesome! It also ignores MKB revocation of host keys. As I recently learned, bus encryption is why official drives, as an example, can't be used as "friendly" drives. So what does this mean in practice? It means, for example, that a drive in LibreDrive mode ignores requests for bus encryption. What it DOES do, however, is bypass firmware restrictions. Again, LibreDrive does NOT mess with AACS at all. You still need a valid title key to decrypt it and AACS 2.1 adds other fun annoyances to the process. It's not going to magically decrypt the content on a disc. LibreDrive does NOTHING to "bypass" AACS.

"Testing a movie like FURY" is pointless. If anyone can point me in the right direction on how to fix this I'd really appreciate it.Ok, let's start with what LibreDrive is.and isn't. VLC is the only program I have that can even play UHDs though, so I can't even compare it against anything. But it must either be an issue with my drive that is only affecting 1 type of disc, or it is an issue with VLC. It doesn't seem like a hardware issue since, like I mentioned, I can make copies of the data on the disc and those play just fine. If I choose to skip menus when I load the disc the seek bar displays an end time on the right hand side that is often accurate to the length of the movie I'm trying to watch (sometimes it's really short but I think it's getting a preview or anti-piracy message in those cases), so it is somehow getting some of the metadata, but it absolutely will not play and I cannot use the seek bar to seek. I can also press stop on VLC and load up a different media source so it isn't crashing. I can hear the drive spin for a bit before it eventually stops. It understands there is a disc in there and what the disc is because the background art changes to a little thumbnail to suit it and the title bar up top reflects it as well, but then just nothing happens. However when I try to play a UHD directly from the disc in the blu ray drive, VLC just sort of hangs.

Playback is fine on when doing this, little to no stuttering or anything. I can then play back the folder created by MakeMKV as though it was a disc getting menus and everything using VLC. I can also rip data from all those formats, and I can rip UHDs using MakeMKV. I can use it and VLC to play any regular blu ray, dvd, or cd I've tested it with.
