UHD FAQ
Re: UHD FAQ
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.

Good news: the Doom9 AACS 1.0 MKBv82 device key is now included with the public keydb, so no additional steps should be required.SamuriHL wrote: ↑Fri Jan 17, 2025 2:43 pmKeyDB Helper (Windows Only)

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
Re: UHD FAQ
Nice. Thanks for letting me know. I'll update my instructions.

Re: UHD FAQ
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?lm144 wrote: ↑Sun Jul 27, 2025 3:27 pmGot a better understanding now.

Re: UHD FAQ
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.
Re: UHD FAQ
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.tbrady3742@aol.com wrote: ↑Fri Aug 15, 2025 4:55 pmSince the recent upgrade of makeMKV, it hasn't been reading my discs.
