Following ChuckPa system guide for installing PMS on a Synology NAS Setup of PMS on Synology I did successfully download the latest PMS from the link and setup a shared folder on my Synology 215j. However, as I expected when I tried to open a film I put in a shared folder set up for Plex, I got the following error.
So obviously my current NAS is not suitable, so looking at getting the Synology 218play which I hope will do the trick.
