I’m trying to backup a Blu-ray disc using MakeMKV, but I keep getting the error: “This disc uses a newer version of AACS protection” and "The volume key is unknown for this disc - video can't be decrypted".
There are four disc with the same issue. Each disc has created an AACS dump file (attached for reference).
Below are the drive info and makemkv output from one of the disc:
