It was actually rather embarassingly easy. I went through the instructions and was having some problems with terminology, so I googled - and there was a solution on the net to go through Windows Media Player and network that way (using options, library, configure streaming). Immediately the WD Live showed up and I could stream.
Also tried TVersity and it can now sense the WD Live and the WD Live is able to pick up the streaming video. Now I just have to figure out how to use them to properly organize my files…
Thank you again for the help.
