Well try this, download Serviio and install it, make a note of your TV's IP address and in Serviio on it's main control panel you will see IP address of any DLNA device on the network (TV might be the only one), for the TV IP address click where it says "generic DLNA profile" text and from the drop down box select Sony N-100 profile.
After that add in a few folders for Serviio to monitor and see if you can connect to Serviio on the N100 after that.
I added Serviio and it shows the movies but not the tv shows. Also it only picked up the 1st media player and my laptop but not the second media player. Did I do something wrong?
