Please read the first post in this thread for some resources/links you might find helpful when configuring MakeMKV to utilise the public keydb.

Yeah, already had that set up, checked first to see if it was in there already.

The change in AACS 1.0 (1080p Blu-ray) support has been due to the latest update to AACS. This is referred to as MKBv82 and it revoked the device keys bundled in MakeMKV which were previously able to derive the disc-specific keys for all AACS 1.0 discs.

There is a publicly available device key which works for MKBv82 but Mike has so far decided against incorporating this into MakeMKV. The lack of a suitable device key is why disc dump submissions are currently required for AACS 1.0 MKBv82 discs.

So it's no longer possible to rip anything without going through this process? That's ridiculous. And it's a disc-by-disc thing not even a release-by-release thing? I'll be getting some TV shows on Blu in the near future, that's going to be an absolute nightmare to go through.

Thanks for the disc dumps hulahoo, the 9DDE variant of Meatballs and the 2308 variant of Daybreakers have been added to the public keydb

That is an interesting way to say 'thank you' to the folks voluntarily contributing to the public keydb and assisting MakeMKV users... Particularly when the keydb contributors are entirely distinct from the MakeMKV development team.

I understand the user experience for AACS 1.0 MKBv82 is a regression compared to the pre-2025 behaviour. But it is also how AACS 2.x (UHD) discs have become supported for the past 7-8 years, so it has been normalised to an extent.

It is absolutely possible for users to generate their own disc keys using the publicly available key from the Doom9 forum. Because you run Windows you can use SamuriHL's tool to generate and submit keydb entries for your discs. Some users find it easier to post disc dumps here as they use Linux/macOS or they want to facilitate adding support for a UHD disc.

And it's a disc-by-disc thing not even a release-by-release thing? I'll be getting some TV shows on Blu in the near future, that's going to be an absolute nightmare to go through.

It is entirely possible your next purchases will already be supported by the public keydb. Otherwise it isn't exactly an ordeal to upload several disc dumps and post the links here.

That comment was in response to the notion that it would apparently be very possible for MakeMKV to support these discs out of the box, but for whatever reason it just doesn't.

How does one do that? I don't see anything in that post outlining a way to generate anything, only locate things that already exist?

Fair enough, sorry for interpreting your comment more negatively than you intended.

I'm not sure why the MakeMKV team haven't incorporated the publicly available MKBv82 device key but there is no technical reason why MakeMKV can't natively support AACS 1.0 MKBv82.

How does one do that? I don't see anything in that post outlining a way to generate anything, only locate things that already exist?

The relevant functionality was mentioned under the 'Disc Info' heading:

...
* Disc Info - Shows you the information for your disc including the disc ID. If your KeyDB.cfg file contains device keys and/or processing keys, it COULD, in theory, maybe use those to ADD entries to the KeyDB. You know, for those pesky MKB v82 blu-rays everyone is loving.
...

The latest public keydb includes an AACS 1.0 MKBv82 device key, so you should be good to go.

If I had to venture a guess, it MIGHT be because of the host cert situation. Up until now, LibreDrive wasn't a requirement for Blu-rays and MakeMKV. And while there's a known device key that works with MKB v82, there isn't afaik a known host cert. Maybe Mike decided to wait until he can acquire a new host cert. Who knows but that's the only thing that makes sense to me.

Yea, it should just work as long as you synchronize the keydb, which you should do every time you run my tool anyway to ensure you have the latest. When you use the Disc Info button, if the keydb doesn't have an entry for your Blu-ray, an entry should be generated and added to the keydb. Since it's using FindVUK under the covers, the validate disc option will do the uploading and validating of the keys to ensure they're correct, all automatically. You won't have to manually click the validate disc button in this case.

I tried that, and it's been stuck on “Starting FindVUK validate disc!” for maybe 15 minutes? No sign it's making any actual progress with anything.

You hit a bug I've been trying to fix but haven't been able to. The very first time you scan a disc with FindVUK on a drive it doesn't know about it tries to warn you that it's a new drive. My code doesn't have a way to move past the prompt that FindVUK is stuck on. Just kill it and try it again and it should work now that the drive's been added.

If by this you mean close the Helper program, reopen the Helper program, and click on Disc Info, no, it still gets stuck at the same point.
