I've setup a home group in Windows 7, added files and folder to a library. DLNA picks up the homegroup but when I try to play most files I get : Sorry, an internal error occurred. The media file cannot be played whilst it is streaming. The odd file will playback, even though it's in the same folder and is in the same format as the files that will not playback. I can playback the files if I copy them from the PC to my phone. I've tried XBMC and Skifta but have the same problem.
