Hi guys,
I al using the DS3617xs for Plex. So after installing Plex I wanted to install other apps to help download en get video's.
Now it seems that the apps are not ready for this NAS yet 
So what I do now is download my video's on my older NAS (1512+) and save them on a share. On the new NAS I use FileStation to connect to the Old NAS using SFTP or WebDav and then it looks like Plex works.
After closing the DSM browser it looks like the connection to the OLD NAS is gone and Plex can't seem to find the files anymore.
On the Nvidia Shield I could connect to a NAS without a problem.
So in short:
-> File Station -> connect to other server using WebDav/SFTP
-> Plex -> add folder on my video's -> go to the Mediafolder -> choose GVFS -> dat:host:192.168.2.50, port=5005xxxxxxxxxx
Maybe this is the wrong way to use a shared folder from another NAS on my Plex server on the new NAS??
I hope I described it correctly and love to hear some tips!
Stefan
