Plex Media Server version? 1.41.x.y, 1.42.x.y, etc.
DSM version?
It is usually naming/organization or permissions, but there can be other reasons as well.
Please show how you have the movies named and organized. A directory listing, screenshot, etc. that includes the folder added to the library and the file’s extension (.mkv, etc.).
Make sure the user Plex (DSM 6) or system internal user PlexMediaServer (DSM 7) has at least read only access to the files. See FAQ 19: Setting permissions to allow Plex access to media files.
If the above does not help:
-
In Settings → server_name → Library, enable
Scan my library automatically(this adds some additional information to the log files). -
In Settings → server_name → General + Show Advanced, ensure Plex is configured for debug, not verbose, logs.
-
Stop Plex Media Server and wait one minute.
-
Start Plex Media Server and wait two to three minutes for it to fully start and log the startup sequence.
-
Scan one of the troublesome libraries.
-
When the scan has finished, pull the server log files (settings → troubleshooting) and post them to the thread. Drag the entire zip file into the message window and wait for it to upload.
