Yes, I did that yesterday, but now I remember with the TGZ containing the AACS/MKB_RO.inf file that had the wrong weight.
I'm sending one back with the replaced file in it.

Thank you very much for your reply!
I have just checked again and LibreDrive is indeed "Enable"
So I'm going to wait patiently and update the keydb.cfg file from time to time until my Blu-ray is added.
Thank you again for your help!

Here is the zipped file.

Unfortunately, I don't have any other drives than the Verbatim 43888.
I didn't think it could be the problem, but following your last answer, I just saw on the forum that I might need to flash it, is that right?

Hello,
I submit this file, because even after updating the keydb.cfg file in the MakeMKV folder.
MakeMKV still cannot decrypt the Blu-ray.
