Blu-ray showing as "PS3VOLUME"

[NinjaBlizzard]

Hi all,

I'm fairly new to the world of MakeMKV and ripping Blu-ray discs. I have an LG BP50NB40 (NB50) drive that I had previously flashed with the BP60NB10 1.00-MK as shown in this guide:
viewtopic.php?f=16&t=22896

Most Blu-ray discs have been ripping with no problems, however I recently tried to rip Battle: Los Angeles and noticed that the disc is showing in File Explorer and MakeMKV as "PS3VOLUME" and I am getting errors trying to rip the disc, but it does rip. I am unable to encode the files in Handbrake, however. I've attached the screenshots with the errors.
I know this is likely related to the AACS version of my firmware, but I was unsure how to resolve this.
Any help would be appreciated!

MakeMKV just shows whatever name the disc's authors gave it. Usually it is the name of the movie, but not always.

If you're having trouble ripping a disc, try gently cleaning it.
