Custom TV shows is not supported at this time and media companion.
The reason is we need a unique ID for custom shows, as at present Meda companion requires the tvdb ID or tmdb series ID to identify the show as well as identify the episodes attached to the show. You'll probably find every time you refresh you get these episodes again and again so you might get four or five of the same episodes.
I had intended to add custom TV series but have not gotten around to it.
I'm trying to find time now that I've got a new job to implement some of these extra features in media companion, it's going to take time.
Sorry you may just have to wait for this feature for a little while longer.

Okay, at least I know I'm not doing anything wrong.
I have a ridiculous amount of hours ahead of me going through and editing all of my home videos so I'm sure you'll be ready before me!!
The other stuff can wait for sure.

Thanks for all the effort :-)
