AACS Version Reported Lower on Linux than Windows - Causing Issues

[formdissolve]

Basic info:
Fedora 43
Windows 10
MakeMKV version 1.18.2
Asus BW-16D1HT with Asus BW-16D1HT 3.10MK firmware (drive didn't work at all in Linux until I put the Libre drive firmware on)

Hello all! I searched the forums and found bits and pieces of relevant info, but thought I'd ask directly here in a new thread.

On the compiled Linux version, the version of AACS that shows upon first load is v65. In Windows 10, the immedate version is v85. This causes issues in Linux where a blu-ray won't load and make horrible seeking noises in the drive.

• AACS version changes to whatever the version is on the disc

• Time jumps to 3 hours + in its attempt to read and decrypt the disc

• After I cancel the process, the AACS version stays the same and I can no longer read even older blu-rays with a far lower AACS version. It can of course read DVDs

• Deleting both _private_data.tar files just makes MakeMKV download the SDF again and it will show the same AACS version and has the same issues

• Going back to Win 10 after it's in that error state, it still won't read Blu-rays

The way I cleared the drive is by going into Windows and reflashing the MK firmware. After that, it works in Windows and Linux, but Linux will run into the issues detailed above again. I have read a few interesting things[1][2] about flashing directly in Linux, but I assume that would still cause an issues with a lower AACS version, thus not being able to decrypt data.

I should be able to get the SDF from _private_data.tar and re-flash, but want to see if something else is causing the issue.

Code: Select all

 
cd /root/.MakeMKV
makemkvcon f -f sdf_00000098.bin -d /dev/sr0 rawflash -i ASUS-BW-16D1HT-3.10-WM01601-211901041014.bin

Has anyone else been able to fix this? Of course there may be more to it. The fact that after it gets in that state it won't work in Windows until I re-flash means something is being stored on the drive somehow. When it's in that broken state, blu-rays won't even mount in Linux or Windows.
