How to correct matches when TVDB and The Movie Database are wrong?

A TV Show Library\
.....The Avengers Earth's Mightiest Heroes (2010)\
.........Season 01\
.............The Avengers Earth's Mightiest Heroes (2010) - S01E01.mp4

Produces instantly:

If you are using MP4 files (or even if you’re not - you may want to at some point):

If you still can’t get a natural match, Fix Match (at the show level - not season or episode level), go to TVDB and grab the TVDB ID #: 192171

and put it here:

Personally, I’d go for the total Do-Over and that’s The Plex Dance (with you fixing file names, folder structures AND moving Local Media Assets BEFORE you add the show back to the server):

That’s pretty much all there is to it.

(Note to Noah - as i KNOW you’ll read this, eventually:
FileBot would NOT find this show, insisting it was The Andromeda Strain. I hand edited the file name/structure I knew it had to be and it was found instantly. I’m gob-smacked…lol)
