Will not match movies anymore

Preparation:

  • make absolutely shure, that your server has accurate date and time (no joke). If necessary, enable the ntp daemon. (might be named differently in your NAS - try ‘time sync’ or ‘set time automatically’ or similarly named menu items)

Judging by the amount of CAPITALIZED movie titles in your screenshot, I’d say your agent configuration gives too much importance to embedded meta data.

Do this:
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 one of the problematic movies.
See what comes out of this.
