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?
