I've just installed a PLEX server on my Synology NAS and it seems to be working well. I can watch media files on my TV.
One thing that has me confused though is that when I go to add a library to the PLEX server and select "Film" for the type and type in the path to the media it says "Your changes could not be saved" but if I do the exact same thing again with exactly the same file path but instead select "Other Videos" PLEX will add the library without any problems. I mean this isn't a major issue as I can still watch the media files on my TV but it doesn't show any downloaded metadata from the internet which is a little bit annoying.
Has anyone come across this issue before? I'm a bit confused as PLEX seems to be working perfectly apart from this.
Oh, and yes I have followed the Film naming guidelines set out by PLEX for this particular media folder.
