Three servers folders each for video, music and photos



Hi, very strange! I use Synology Nas PMS for stream mainly on my Samsung BD C5500 Dlna device.
But what I have on the app installed on the DLNA device is 3 servers: In fact I have 3 folders for video, 3 folders for music and 3 folders for Photos. I uninstalled and reinstalled almost twice . I tried also to delete manually on DLNA 2 servers (but the resutl in this case is to missing Libraries)
This is not merely aestetic. In fact when I search for a video I must check , one by one, the 3 folders Video.
How can I set up to have 1 Server, 1 Library for Video, 1 for Music and 1 for Photos?
Thanks in advance


Any hints?
