Created filename does not match selected one

[CosmicTourist]

When I use MakeMKV and insert a BluRay disc, I make sure, before I click on "MakeMKV" that the title of the save file matches the title of the disc itself.

But when the file creation starts, the filename is a generic one, like "title_00.mkv"

Why does the program not name the file as I have intended?

I am using the latest version of MakeMKV.

If the disk does not include the title in its data, you'll get "title_NN" for the displayed name. Some disks have a name included; MakeMKV uses it, rightly or wrongly.
