How do I make the DVD-collections show up in Kodi?



So, I have a little Problem with a DVD collection, that won’t show up in my library.

I had the complete collection of Loriot backed up.

How do I rename the folders or files, to make it show up in KODI ?

episodes in KoDI.
Should I maybe connect all video-files and stitch them together (per disc) ?
I really don’t know how to proceed.
