AACS v82 dump

Post by nik4nao »

Hi,

I tried to open this disc with MakeMKV and got the following message:

Code: Select all

This disc uses newer version of AACS protection.
Saved AACS dump file as C:\Users\<username>/.MakeMKV/MKB_v82_TBXK_1405_B94A.tgz
The volume key is unknown for this disc - video can't be decrypted.
Backup failed.
Dump file attached.

Thanks!
Woodstock

Did you email the file to svq@makemkv.com ? Otherwise, it will not be added to MakeMKV's configuration.

Attaching the file (which didn't work; is it bigger than 4.0mb?) is for the keydb people. Most people upload those to a public storage site (google is popular) and provide a link in the message, rather than attaching a file.

Thank you for the reply!
I just emailed them the file. Didn't notice the file didn't actually get uploaded here.
I guess I just have to wait until it's patched.

Thank you again!

Alternatively, you could upload your TGZ dump file into (say) OneDrive or Google Drive, and then reply with a public download link. This would allow people to try adding your disk to the public KEYDB.cfg file as well.
