Someone please help!

I’m having the same problem.  I have a Mac Pro and am trying to stream Video_ts from it to the WD-TV live box.  In setup on the WD-TV it sees my TIme Capsule Router and a computer called “macintosh,” although my mac’s network name is different.  I plan on spending some time with tech support on the phone tomorrow and after reading your post not looking forward to it!  I wonder if there are any other products like this out there?
