I think at least a part of these duplicates could also be caused by:
- downloading/ripping movies directly into a folder which is being “watched” by Plex. Don’t do it. Cure this with the Plex Dance – particularly if your library is still using one of the old Python-based metadata agents.
- preferring embedded meta data over metadata supplied by Plex. You can cure this as follows:
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
If the library in question already uses the new metadata agents, do this instead:
- Edit the library,
- go to the ‘Advanced’ tab,
- clear the checkbox “Prefer local metadata”.
In some extreme cases, you might wanna perform the Plex Dance here as well.
