Good to know my original understanding was on the right track.

The MK for that Spaceballs variant has been in the keydb since April 2025 and the VID wasn't obfuscated as the disc dump was generated with a Buffalo branded BU40N variant. The verification data in the dump file indicates that bus ...

Sorry about that ShootTheCore. I think I may have misunderstood how the KeyDB Assistant tool processes partial disc dump files. Glad to hear you are all good now.


No it should have worked. If there was an MK available it should have been able to calculate the UK. The only exception would be ...

Nice work on the update, those are some really neat inclusions.


Thanks, yea I thought they might prove useful. Given that my work is mostly a front end for findvuk and makemkv, scripting the backup call to makemkvcon wasn't a huge lift. The logic around dealing with unencrypted discs with bogus ...

1. Backup to folder (leave decrypt unchecked)
2. Delete the AACS directory
3. Open index.bdmv in MakeMKV
4. Create MKV file.

No. (You'll see why shortly)

Yea that’s all findvuk under the covers. Disc info is mine. They really don’t interact at all.

Yes. Nothing I have can play that actual layer from an MKV anyway. The TVs show they are playing Dolby Vision, but they aren't actually playing the FEL layer.

Besides, I still have the ISOs of the rips, from Xreveal. So, I can always go back to it if I ever need to. And run MakeMKV on it.

The ...

When I get a minute I need to test those discs with my KeyDB Assistant. In theory, it should detect that they're not AACS encrypted and warn you when you do a Disc Info function. I haven't yet ripped my set but will be doing so this week and when I get to those discs I'll see if the detection works.

Thanks for the reply. Interesting. So are you saying to literally copy the contents from the disc to hard drive, say with Windows File Explorer and essentially ignore/do not copy the AACS directory then point MakeMKV to that copied folder structure?


Sure or use the MakeMKV Backup function and ...

Yes, they're not encrypted. This has been established in several threads already. Backup to folder, delete the AACS directory, and it'll open just fine in MakeMKV.

(This is only true for certain discs)

Doesn't that mean you've lost the Dolby Vision FEL layer, however?

I did it slightly differently and in the end did not end up using MakeMKV for this. I have the CE but I doubt it makes any difference.

Ripped both discs to protected ISO
Mounted them (I use ImgDrive, use whatever you want) both
Make sure XReveal is loaded for this one
Open MKV Toolnix
Add 00001 ...

Mine was supposed to be delivered today but has been delayed. Hopefully Monday. I'll see if I have the same issue. May be a mastering issue potentially or just a bad batch of discs.

No, all good. If people still find it useful that's great. Thanks for posting it.
