Try running it through Handbrake?

Failing that, it could be worth trying it in Linux. It’s not too hard to spin up a VM, and libdvdcss would have the codecs you need.

Ah, I stand corrected.

That’s a good idea. Why didn’t I think of that?

The boot issue is definitely hardware related. The machine doesn’t even power on the display before restarting.

Three reasons for me:

1. DNF can be kinda slow
2. Fedora is owned by Red Hat, which is owned by IBM, which is American and also assisted the Axis powers during WWII.
3. SELinux was created by the NSA. I know it’s FOSS, but I don’t feel I can trust any three-letter agency.

I never really got on with Slackware, but I might give it another shot…

I’m asking for advice.
