There have been packaging changes since the initial rollout of PMS on DSM 7.
The primary change is the addition of the /plexmediaserver shared folder. This is where Plex stores its internal information (database, etc). DO NOT put any of your media files in that folder. It is reserved for Plex internal use only.
