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.

Re: UHD FAQ
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.

Re: UHD FAQ
I'll have to check that out. Also, I have seen that ASUS is supposed to be under System Devices. Have you noticed if your writer is located in there?Blyth wrote: ↑Fri Aug 15, 2025 8:13 pmHave you got any CDs to try load one up and see if it plays ok, just to see if its Windows playing up.

Re: UHD FAQ
It will show up in device manager if it isn't then something is not right, at a guess I would say it's faulty or on its way out.tbrady3742@aol.com wrote: ↑Sat Aug 16, 2025 4:04 pmI'll have to check that out.

In device manager click on scan for new hardware, but it should automatically pick it up.

Re: UHD FAQ
yeah, it is listed in device manager. I had seen on another section in here that it should be listed under SYSTEM DEVICES. Looks like all the devices that are connected to computer. Didn't check before updating makeMKV so not sure, but hasn't been working since I updated it.Blyth wrote: ↑Sat Aug 16, 2025 7:48 pmIt will show up in device manager if it isn't then something is not right, at a guess I would say it's faulty or on its way out.tbrady3742@aol.com wrote: ↑Sat Aug 16, 2025 4:04 pmI'll have to check that out.

Re: UHD FAQ
If you think it's the software you could uninstall MakeMKV with Revo Uninstaller then restart the computer and then install again, remember Restart not Shutdown.tbrady3742@aol.com wrote: ↑Sun Aug 17, 2025 12:37 amyeah, it is listed in device manager.

It should be showing up in System Devices, have you clicked on View More Devices?
