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.
