The volume key is unknown for this disc...

Post by maiks »

I copied a complete BR to disk without problems, but still run in problems:
MakeMKV v1.14.7 win(x64-release) started
Opening files on harddrive at D:/Media/Video/6sense
Loaded content hash table, will verify integrity of M2TS files.
Saved AACS dump file as D:/Media/Video/MKB_v9_unkn0wn_3552.tgz
The volume key is unknown for this disc - video can't be decrypted
Failed to open disc

Any ideas?
Thx

I'm not sure what you mean by the first sentence. It sounds like you have dragged the folders from the disc to your hard drive?

You cannot just copy the folders off an encrypted disc to your hard drive and then try to decrypt that.

MakeMKV uses the disc as it's source so it can get the volumeID and calculate the decryption keys.
Cheers :D
