Device and Host keys are revoked in a new MKB versions. Once you have a new MKB v83 disc (not a thing....yet) then it'll likely revoke the device key that's been leaked. All current host keys are revoked in MKB v82. But with LibreDrive, we don't care. We only care about device and processing keys IMO.

Link updated in my post. Accidentally linked to an old tool that doesn't really work. Please redownload if you downloaded the old tool.

Like, if you visited this page:

Code: Select all

...
Good news: the Doom9 AACS 1.0 MKBv82 device key is now included with the public keydb, so no additional steps should be required.
Public KeyDB Disc Submissions
  • LG/Buffalo/Asus drives only (Pioneer drives are not supported)
  • Please use file hosts, not forum attachments
  • If your disc dump is under 3MB, you need to manually include the MKB_RO.inf file from the AACS folder

Got a better understanding now. Thanks so much :)

Since the recent upgrade of makeMKV, it hasn't been reading my discs. I sent the drive info to Billy and he said everything looked fine to him but still won't recognize it. In windows explorer when I put a blu-ray in, it lists the title but not for a 4K. Has anyone else have this problem?

Nope. Sounds like an issue with the drive and/or disc. If Windows doesn't recognize it there's an issue in one of those two.

Have you got any CDs to try load one up and see if it plays ok, just to see if its Windows playing up. You could also try safe mode.
