Plex changing the names of movies to English instead of keeping them native

As long as you use an agent linked to an online database such as The Movie Database, Plex will always use the official title from that database. It only keeps the file’s name for Personal Movies.

By the way… shouldn’t the title of this particular movie be “Winnetou és Old Shatterhand a Halál Völgyében” (hence Movies > Winnetou és Old Shatterhand a Halál Völgyében (1968) > Winnetou és Old Shatterhand a Halál Völgyében (1968).m4v)?

Plex will only consider embedded metadata if you have activated “Local Media Assets” in Settings > Server > Agents > Movies > ... and the library settings (library: Edit > Advanced > Use embedded metadata).

However… before we mix up tons of different topics and create even more confusion…
Can you fix the file name to match The Movie Database title and re-scan the library, wait 1-2 minutes and then get your logs and attach them here?
