Casablanca 4K ripping issue

Post by tboyer »

The first week of July I purchased the 4K Blu-ray version of Casablanca (upc code 883929788590). I attempted to rip it using MakeMKV with one of my supported optical drives. The rip was not successful – The volume key is unknown for this disc. I attached the AACS dump file MKB20_v77_Casablanca_4B2D.tgz to an email and sent it to the appropriate email address so MakeMKV could process it and add my disc to its known files. I have been on the latest version (v1.18.4).

Tomorrow is September 1st and Casablanca 4K is still not recognized by MakeMKV. I sent a second dump file mid-July just in case the first email didn’t make it to its final destination.

I have had to send dump files for other 4K UHD discs that were newly released - and understandably not yet found. Within a week or two they are were found and ripped successfully. Casablanca is the only 4K I cannot rip out of my 200+ 4K discs.

Here are the results attempting to rip in MakeMKV with logging turned on.

Using LibreDrive mode (v06.3 id=4083C4CCDB14)
Using direct disc access mode
Loaded content hash table, will verify integrity of M2TS files.
Saved AACS dump file as C:\Users\xxxxx/.MakeMKV/MKB20_v77_Casablanca_4B2D.tgz
The volume key is unknown for this disc - video can't be decrypted

Any thoughts as to my next steps?
