Schindler's List missing key

[dm29_]

Hi! Seems that MakeMKV (1.15.2) doesn't have yet the key for decrypting these title. The data:
Disc Information
Label: SCHINDLERS_LIST
Timestamp: 2018-11-27 15:50:22
Data capacity: 89.21 Gb
Disc type: BD-ROM UHD
Number of layers: 3
Bus encryption flags: 80
The error: The volume key is unknown for this disc - video can't be decrypted
Failed to open disc

There's some comments about these title in the forums so I'm a bit puzzled.

Thanks in advance.

strange, succesfully worked for me 3 days ago

There can be different keys for discs from different countries, best to send a dump in as advised.

So I did. Thank you!

Guess what. I did nothing ... and it worked! I made a backup and decided to experiment with it and just decrypted it. No MakeMKV updating or anything. Simply, somewhat, knew the key this time.

Any idea on what happened? For sake of curiosity.

MakeMKV will download keys silently. It probably downloaded the key for your copy of the movie. If you look in your data directory (as specified in preferences) you'll find a file named _private_data.tar where the downloaded keys are stored.
