I recently bought a collector edition boxed set of a 1970s martial arts series I love. I can’t even play it in VLC, makemkv beta code situation is borked, and handbrake scans all the titles, then says there are none.

I have a local Plex server I wanted to use, no other devices that can play Blu-ray other than an external USB drive I just bought.

Any advice? The Linux box is on 22.04.
