Hello,

I encountered an issue with a new disc that seems to use MKB v82.

Disc title: ぼくのお日さま
Drive: LG WH16NS40 (firmware 1.01, manufactured May 2023)
MakeMKV version: v1.18.1 (darwin arm64)
LibreDrive: enabled

The disc fails to open with the error:
"The volume key is unknown for this disc - video can't be decrypted"

I have attached the AACS dump file as requested.

Thank you for your support!

There is no attachment. Probably, it exceeds the 4.0MB limit, which means you'll have to post it on a different site.

The upload that MakeMKV uses is one you email to svq@makemkv.com , as Mike does not visit the forum often enough to handle them being posted here. However, the keydb people can, if it is small enough to post.

As Woodstock said:

1. You should always email your dump file to svq@makemkv.com
2. If you want to also help the community and have a record for your disc added to the public KeyDB, host your dump somewhere and paste the download link here.
