I’ve just been adding ripped Bluray files (.mkv) to an existing folder structured:
/Series Name/Season X/SXXEYYYY Title.mkv
Despite having the same format through 26 seasons I’m only seeing about 2/3 of them on Plex though those that have scanned don’t have the complete listing inside.
I’ve tried rescanning, moving the parent folder then replacing and rescanning, renaming the parent folder and rescanning but I’m still not seeing the episodes where they should be.
Under Plex if I change the view to ‘folders’ I can see all the missing episodes under the one parent, they just don’t show up on the normal TV Show/Title view.
The missing ones include items that were previously visible, so it’s not that the files are unreadable. I can still play them from the folder view.
And no change in permissions either.
I’ve also tried unmatching and rematching but again it scans through, finds the files for the earlier seasons, then ignores the later ones.
You might adjust your filters to show duplicates - that can quickly determine if you’ve got different files matching to the same show by accident. That’s the most common “missing media” for me anyways (I don’t always follow the naming rules exactly sometimes when I’m being lazy).
Switch the Library view to Episodes (instead of TV Shows) and then adjust the filter to Duplicates:
