VUK found in KeyDB_Helper but makeMKV can't decrypt

#1 Post by Loki7571 » Tue Dec 23, 2025 11:03 pm

I use SamuriHL's KeyDBTool for Windows and search my disc ID there and it found the key there like this:

Code: Select all

[KEYDB_STATUS]: (VALIDATED)
[MakeMKV SUPPORTED]: TRUE
I have already copied the newest keydb.cfg file to my C:\Users\USER\.MakeMKV directory but makeMKV stills fails to decrypt:

Code: Select all

The volume key is unknown for this disc - video can't be decrypted
Failed to open disc
What could be the reason?
Thanks in advance

You did extract the file from the zip?
It is a physical disc and not an ISO?
Cheers :D
