AACS dump – decryption failed

Hello,

I tried to open the Blu-ray disc using MakeMKV v1.18.1 on Windows 10,
but it failed with the following message:

"This disc uses newer version of AACS protection - The volume key is unknown for this disc - video can't be decrypted."

I have attached the AACS dump file generated by MakeMKV for your reference.

Thank you very much for your support and updates!

Did you email the dump to svq@makemkv.com so that it can be processed? Posting on the forum doesn't work if the file is larger than 4.0MB, and doesn't help getting support in MakeMKV.

Making a link to a separate upload, however, helps with the keydb database, which can be used by MakeMKV...
