I've no idea what server version or how to find out, it's built into my TV recorder?
Restarting the app got into the user interface and it could see the DLNA server and let me navigate folders and play content.
All seemed great until I realised I cannot pause or in fact do anything during playback other than hit the back button. Which is somewhat limiting... But I don't know enough about DLNA or Roku to have any idea what the correct functionality should be and if problems are down to server or client. I'm assuming the obvious control buttons on the remote are supposed to work?
