Have you tried downloading the latest KEYDB.cfg file, copying it into MakeMKV's data directory (i.e. where MakeMKV also writes its TGZ dump files) and restarting MakeMKV?

[uhd-4k-fan]

Yes, did that.
Also check the disc ID and the disc is not in KEYDB.cfg, yet.

[uhd-4k-fan]

Dump as attachment if someone can make use of it to get it added to the keydb.
Be aware the dump is created using a Pioneer drive.

If you're a Windows user then you might be able to decrypt your disk using MakeMKV with Xreveal. This would only require KEYDB.cfg to contain a Unit Key ("| U |" record), instead of needing a Volume Unique Key ("| V |" record).

That dump is highly broken. Nonetheless the full record including the VUK has been uploaded to the KeyDB.

Actually, that dump was created by a Verbatim 43888, which means that the VID is almost certainly wrong. And hence the VUK calculated from it will be wrong too .

Hopefully the Unit Key still checks out though.

That means there's a bug in my code as it checks for that situation...I'll deal with that. So yes, the VUK that's been uploaded would be wrong. That sucks.

If anyone happens to have that disc and can make a non-verbatim pioneer drive dump and can post it that would be helpful.

Even more useful, could any Windows user who has this disk please validate its KEYDB entry using FindVUK? Specifically, and assuming your UHD drive is F:

• Edit your FindVUK.ini file to contain

  Code: Select all

  Disable_Bus_Encryption_Cmd = "C:\Program Files (x86)\MakeMKV\makemkvcon.exe" info dev:$DRIVE$

  assuming you have installed MakeMKV in "C:\Program Files (x86)\MakeMKV".
• Execute

  Code: Select all

  findvuk synchronize

  to ensure FindVUK's copy of KEYDB.cfg is up-to-date.
• Then put your disk in your UHD drive, wait for Windows to mount it, and then execute

  Code: Select all

  findvuk validateDisc drive=F

The relevant record in KEYDB.cfg starts with:

Code: Select all

0x60FD85412E2AFBFBDB39BD160A5308CBB1497BDF = BLUES BROTHERS 4K UHD EXTENDED (The Blues Brothers 4K Extended Version - Blu-ray™) | D | 2022-06-14

I strongly suspect that both its Volume ID ("| I |" field) and Volume Unique Key ("| V |" field) are incorrect, although both its "| U |" and "| M |" fields are probably OK. In which case, deleting both the "I" and "V" fields should allow "findvuk validateDisc" to succeed.

This is probably the only way to correct the record .

[SamuriHL]

Very likely. This particular dump file was problematic which exacerbated my code's issue. It'll be fixed for next time.

[uhd-4k-fan]

New dump with a different drive.

[SamuriHL]

Looks like someone already fixed that entry in the keydb. It should work with MakeMKV now.

No, that entry's VID and VUK still look broken to me . However, I am confident that running

Code: Select all

findvuk validateDisc drive=<your uhd drive letter>

could fix it.

[SamuriHL]

Yea I tried uploading the fixed entry and it won't accept it. When I resynced the keydb it reverted what I changed. Lovely.

[uhd-4k-fan]

findvuk only gives me:

Code: Select all

-------------------------------------------------------------------------------
09:47:37 - Get basic AACS data
-------------------------------------------------------------------------------
09:47:37 - AACS folder on disc is reachable - Validate is possible
09:47:37 - Failed to init disc >AACS UNKNOWN ERROR >-1501<<

But it rips fine with MakeMKV HK now.
