Can't read AACS VID from disc even with LIbreDrive
Posted: Sat Sep 10, 2022 2:52 pm
I have 2 BU40N drives that for the most part have been working fine for ripping. Both are flashed with the 1.03MK firmware per the Ultimate UHD flashing guide and report in MakeMKV as having libredrive enabled.
However, after I started ripping my most recent discs that I bought, all of a sudden I'm getting
and
errors when trying to rip UHD discs (only UHD discs, regular BR is fine). I even tried with a disc I had previously ripped successfully and it results in the same error, leading me to believe there's definitely something up with the drives themselves.
From what I understand about LibreDrive though, is that it shouldn't matter if host certificates are revoked since MakeMKV can access the disc directly (and indeed, the logs say "Using direct disc access mode"). Every forum post I come across (such as this one) regarding the above error is always "Use a libredrive compatible drive + firmware", but I'm already doing that AFAIK.
To add to the mystery/frustration (however you want to look at it), I am also unable to even make encrypted backups of these discs to try and remove the drive itself from the equation. MakeMKV spits out the same errors as above at the beginning, and then every .m2ts file is reported to be corrupt.
Clearly I've screwed up somehow, I just have no idea what I did wrong. Any help would be greatly appreciated.

Recently bought disc of same AACS version that also does not work:
Recently bought disc with AACS v76 (I suspect this one is the culprit due to the higher version, even though v76 is supported the current MakeMKV version):
