TV Show Episode Name Generation?

Get Filebot or similar software.
So at least the space/dot between the season and the episode number should be gone.

The affected files are in mp4/m4v format, right? The ugly titles you are seeing come from the embedded ‘Title’ meta tags in your files. To mitigate easily, do this:
Go to

  • Settings - Server - Agents - Shows - TheTVDB

In there, grab the line ‘Local Media Assets’ with your mouse and drag it downwards, so it ends up being at the bottom of the stack of active agents.
Repeat the same under

  • Settings - Server - Agents - Shows - TheMovieDatabase
  • Settings - Server - Agents - Movies - Plex Movie
  • Settings - Server - Agents - Movies - TheMovieDatabase

Afterwards, ‘Refresh Metadata’ of the affected shows (not ‘episodes’, but the whole shows!)

The alternative would be to remove all embedded meta tags from each file and then again ‘Refresh Metadata’.
