I am using JRiver Media Center in combination with a Moon Mind 180 streaming device via DLNA.
In Mc 18 is experienced some occasional drop outs... following by some time where MC had difficulties to find the streaming device again. Sometimes rebooting the modem for 10 times or so helped. sometimes I just had to wait several hours. Sometimes it work for just 3 songs. When it worked it did work very consistent until something happened like a crashing MC or a laptop running out of power, or after windows update. Then all troubles started over and over again (dropping out for some tume after some songs until it suddenly start working without problems again....
I upgraded to MC 20 and I experience exactly the same behaviour. It worked most of the time.
But now for a week MC does not recognise the media renderer anymore (windows 8 does recognise it though).
I updated firmware, resetted al settings, reinstalled Media Center 20... but nothing helps.
Please help me checking some things... since all my playlists are in MC and I really love the functionality and the Mind 180 is a wonderfull device.
