m4v files can have embedded metadata. If they contain the movie title without a year, it will overrride the file name.
Perform the following configuration change to reduce the influence of 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 with the mismatched movie file.
