I have a number of TV show disks that I ripped to .ISO files long ago.
When I play them as .iso files, they work as I expect, but when I run them through MakeMKV I get only one episode. I'm sure this is something simple, but I don't know what it is.

How do I set up MakeMKV (running behind MakeMKV Batch Converter) to get all the episodes?

Are you certain that the DVDs had the episodes coded as separate blocks?

What does it look like if you try the original DVD?

Which series?
