Considering the "Backup" feature is for BD only, it isn't surprising it didn't work.

Huh, would you look at that, MakeMKV has a "Backup" function - never used that before. Bad/coincidental choice of terminology on my part when describing the issue.

The issue I had experienced occurred when using ...

I had the same slew of errors reported when trying to make a backup. Turns out I had the DVD disc in the drive. Swapped it for the BluRay and everything works perfectly.

Not sure why it had such an issue with the DVD backup...

Edit: v1.8.5, Korora Linux 19, x64, GNOME. BluRay + DVD + Digital ...

+1. Runs great under Korora 19.

I use MakeMKV to rip all of my original, paid for BluRay movies, keeping the discs in pristine condition. Especially useful when you have a small one running around the place!
