is considered zero, it’s only going to match other content with the same value. Can you elaborate on “I did change the name of the key for the rating variable in the metadata to be ‘MPAA rating’ instead of the default which I think was ‘rating’ before since I found it confusing.”? I suspect we’re zeroing (ha ha) in on the problem.
Yes, modifying the value is going to break the mappings (see https://github.com/jellyfin/jellyfin/blob/master/Emby.Server.Implementations/Localization/Ratings/us.csv). Anywho, I think we’ve discovered the root of your problem. How you choose to rectify it I leave to you! Personally, I’d recommend suffixing your filenames with
[tmdbid-123456]
as per https://jellyfin.org/docs/general/server/media/movies/ and letting themoviedb.org handle it all for you.
