I’ve installed TVersity Media Server Version 3.7.1 (free) on my PC and started the Media Server. I even went into the Control Panel of the PC and set the media streaming options to allowed for the PC. But when I go into the Homecenter of the WOW Ultra TV box, I can’t get it to find the PC so I can’t access any of the files on there. I know that the TVersity Media Server is able to access my files because I can log in via the Chrome Browser to http://localhost:41952/client/media.html#200 and see them.
WOW Ultra TV box is not officially supported so I cannot provide guidance for this specific box.
