Streaming issues

I"m trying to stream to my WD TV live Hub when I launch a video from my computer,  it times out without an error message or says that the device is not responding. The hub is hard lined into my router, and mapped on my network and I can move files back and forth from my computer to the device, any suggestions?

You may try resetting the Hub, by holding its reset button for 4 seconds.  You may also power cycle your router, and try from another computer, in order to compare results.
