So, in your Disc Info comment, can you add the steps so people know what to do?

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

Copy that. So handling the return code from FindVUK could still work, but I get it if you don't want to add it for this edge case.

Backup to folder (with decrypt unchecked). That's important, or you'll be buggered right back in the same spot failing to decrypt the disc.

Explaining the workaround would save / would have saved us poor souls countless hours, but I would understand if he's reluctant to add output about another specific app (MakeMKV).

Since it's a known issue, do we know why this hasn't been prioritized to get fixed in MakeMKV (other than 'all features are unimplemented by default')?

No. :P (You'll see why shortly)

KeyDB Assistant v1.1.0.1 Released — New MakeMKV Folder Backup & Settings
This update adds a MakeMKV folder Backup feature and a related settings option.
What's new:
• New Backup button on the main toolbar.
• Creates a full folder backup of the inserted disc using makemkvcon64 backup.
• If a matching key exists in your KeyDB, it creates a decrypted_<DiscTitle> backup.
• If no key is found, it creates an encrypted_<DiscTitle> backup.
• Special handling for discs with a bogus AACS folder where the content is not actually encrypted: the backup is run in MakeMKV's encrypted mode to avoid corruption/failure, the output is labeled decrypted_<DiscTitle>, and the AACS directory is automatically removed afterward.
• Backup Folder Location setting added to the Settings dialog.
• Disc Info now detects non-encrypted discs and recommends using the Backup button; it also notes that the resulting folder backup can be opened directly in MakeMKV.
• Live MakeMKV output is displayed in the status window during backup.
• If a backup folder with the same name already exists, you are prompted to overwrite it.

Please provide a new link or better open a new thread that is separate from UHD FAQ. Sending people there would be much easier.

Thanks! It still needs a search to point users to it. A new thread "KeyDB_Assistant (with underline) would it make much easier to find. Note the underline. The search function in this forum doesn't like short key words to look for.

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

I've experienced the short key word issue when searching for specific disc ID values. But I'm seeing the same results when searching for "KeyDB_Assistant" as I do when searching for "KeyDB Assistant". The search result page seems to indicate the effective query is the same:
Searched query: +KeyDB +Assistant
Public KeyDB Disc Submissions
  • Please use file hosts, not forum attachments
  • You must include the MKB_RO.inf file from the AACS folder on your disc
  • Place the extracted keydb.cfg file in the same directory as your disc dump files

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 AACS directories was the real work behind it. But then using the decrypt backup option when you have a key in the keydb for a title was also nice to have IMO.
