Plex seems to be not merging duplicate movies by default now. If I happen to add another quality of the same movie to my library (even when the extra file goes into the same directory) Plex is splitting them. I can’t seem to find any administrative setting to control this so at the moment I’m having to browse the library, select the two movies, and perform a merge.
Ah, interesting! My usual approach to ‘upgrading’ a file is to do the following:
Add better file to the same folder.
Scan library so it detects the change and adds another version.
Delete the older file.
Scan library again.
This tends to prevent the item as being displayed as newly added to the library.
In the two cases I tried today, I was replacing .avi files with the following name format: Movie Name (Year).avi
with .mkvs with the retained scene name (e.g. Movie.Name.Year.720p.Bluray.x264.DTS-group.mkv).
I’m usually replacing mkvs with mkvs, and I’m pretty sure they’re merged regardless of the way in which the file was named. Perhaps file extension is coming into play here?
To be clearer, the merging is based on if a file gets matched to the same movie, which is mostly based on filename. If Movie.Name.Year.720p.Bluray.x264.DTS-group can be matched to the same movie, then they should get merged. If they are not merging, check the xml for each version and make sure they use the same agent. Movies from different agents are treated as different movies.
