Metadata Cache

Does Plex.tv cache metadata that is pulled from the Movie DB.

If so how long is it it held for.

themoviedb.org/movie/444608-jagveld

Returns different Artists and Posters than Fix Match does.

Is your movie even matched to TheMovieDB? (The default data source is the IMDb)
Take a look at the movie’s Plex XML info to find out. Look at the guid="

If your movie is matched to the IMDb, there is a selector in the properties of the Plex Movie agent. ‘Cast list source’ must be set to ‘TheMovieDatabase’

Is it a mp4 file?
These can contain actor infos as embedded meta tags.
By default Plex prefers embedded metadata.
Here is how to switch that around:
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

This is the XML from the file info.

OK, this confirms the movie is matched to TMDB.

Wait a few days.
After that, you may want to empty the local agent cache of your Plex server:

Thank @OttoKerner. That fixed the problem.
