mp4 files can contain embedded metadata. If the file internally still contains a different title or season/episode number, Plex will mismatch it, unless you tell Plex to disregard embedded metadata:
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, perform the Plex Dance, otherwise Plex won’t “forget” the wrong match it has in its database for this file.
