Hello you smart people.
New here first time UHD MKV.

In my attempt to MKV The Dar Knight UHD I was unable to due to: Highest AACS version: 68
from what I've read so far is that this is due to it being a newer pressing of the movie.
because of that Libre Drive has not included that in its library? if I understand correctly.

Not expecting any hand outs but would welcome any advise.
I've patched my Verbatim UHD blue-ray drive firmware to 1.03
as far as I know that is all that's needed?

p.s
The UHD case came with the base blue-ray which I was able to MKV with no issues.

This has nothing to do with the "highest AACS version". It's extremely likely that your issue is due to MakeMKV missing the Volume Unique Key for this disc, and therefore it cannot decrypt the UHD disc. Hopefully MakeMKV generated a dump file when it was unable to read the disc. Send this tgz dump file to svq@makemkv.com

Also, if you want to get it decrypted faster, please follow the instructions in this topic : viewtopic.php?t=38293

...But before doing those two things, please do make sure MakeMKV is downloading the HK (Hashed Keys) properly and that you are not geoblocking Russia when launching MakeMKV.
