Metadata and various versions of a movie

In my experience Plex does not match 10% of all movies correctly. Most of these mismatches are due to the fact that quite of number of movies have various remakes from different years. I usually have the oldest / original version. Plex picks usually the last/newest one. Q1: Is there a setting in Plex where one can force Plex to chose the oldest one. Q2: When fixing the match manually, it seems to take too long to search and update to other metadata (more than 30 sec; where in for instance JRiver, using the same meta-agents, it takes less than 2 sec’s. Moreover the choice of fixing match is not part of the default menu on a cover. You have to press first on the cover and then go back and the “fix match” is visible.

The Big Sleep (1946).xxx
can’t be ‘mistaken’ for
The Big Sleep (1978).xxx

So, basically if you follow the Media Preparation Guide you won’t have this issue - for Movies:

No matter what you do TV Shows are going to be a PITA. Plex decided it was a good idea to undermine their ONLY TV Show database by defaulting everything to the most recent ‘version’ and now it’s all messed up:

Users have to add a (YEAR) field to every older TV Show with a modern remake and if several similar TV Shows have the same (YEAR) Plex spins in circles like it has one foot nailed to the floor.

Thanks for the answer. I am still wondering why the agent lookup takes so long. A similar lookup with JRiver from the same sources is done in a few seconds. Plex seem to take forever.

This is explain in another thread. The gist of it is, PLEX wants to limit the number of queries to the database.
