I’m think the old scanner used it, and I thought I remember seeing it in some official Plex documentation but maybe not. There was a top Reddit post recommending doing this and this thread: Plex server to look for a .plexmatch file when matching a show/movie
So another question:
What if I were to include the TMDB # in addition to the IMDB?
Would that lead to better matching (ie. fallback for when a title doesn’t exist on IMDB)?
