Meanwhile, my Blu-Ray drive (/dev/sr0) is not recognized at all, even though I have access to it with various other programs, such as Xine, MPlayer, etc., and I can also mount disks in the Blu-Ray drive.
Wondering if it might be a Linux-related problem, I even installed the trial version again, this time in WindowsXP, then booted into that using my dual boot capability.
Once again, MakeMKV fails to see the Blu-Ray drive at all.
What in the world am I doing wrong here?
Is there some way to force MakeMKV to see my Blu-Ray at /dev/sr0?
Is there some kind of compile time option I need to build into my kernel, or some kind of kernel command line I need to execute to get it to work?
Also, why in the world won't XP, ordinarily an OS that works when all else fails, work?
I'm completely mystified.

I then tried to force it into working by mounting the disk in my Blu-Ray drive ("I Am Legend," for what it's worth), then pointed MakeMKV to it using the "Open files" command, going into [mount_point]/AACS/MKB_RO.inf.
It seems to see all the information there, seems to try to decode it, then errors out with the following message.
MakeMKV v1.6.16 linux(x64-release) started
Opening files on harddrive at /mnt/dvd/
The volume key is unknown for this disc - video can't be decrypted
Failed to open disc
I don't get it.
This movie has been out for some time, so I just don't believe the key is unavailable.
I'm also under the impression that the program is failing to access the Net to retrieve updated keys.
I'm stumped, folks.
