MEGAN - The volume key is unknown for this disc

Post by Sayjimwoo »

Out of about 100 UHD discs copied. This is the very first one to fail. The dump file is attached.

Using direct disc access mode

Saved AACS dump file as C:\Users\xxx/.MakeMKV/MKB20_v77_M3GAN_AF42.tgz

You need to email that dump file to svq@makemkv.com.

But in the meantime, the latest KEYDB.cfg file contains these entries:

Code: Select all

0x33AE8D89968B358D8F35DBB93A00423E5826128C = M3GAN (M3GAN) | D | 2023-07-10
0xDE8F1B801448E19CA806698530FFD58CBBF92683 = M3GAN (M3GAN) | D | 2023-07-10
0xC7A90D96C3569172DDA36CA8CBB69D0723EF0BCC = M3GAN (M3GAN) | D | 2023-07-10
0xD8395BB2BBE89B44F3B34C95035EDD87ACFCD2FD = M3GAN (M3GAN) | D | 2023-07-25
Does copying this file into MakeMKV's data directory (i.e, where MakeMKV also writes its TGZ dump files) and then restarting MakeMKV help?

Thank you so very much. I emailed over my dump file and downloaded the latest KEYDB.cfg file, which works perfectly. I am currently ripping MEGAN as I type. Thanks again :)

That dump has been submitted before, in February and in March and November, 2023. I'm surprised it wasn't available.

I'm glad it worked for you with the KEYDB.cfg. It is curious that no hashed key seems to be available.
