I have a TV card and Window XP Media Center, and installed Ffdshow(free software) to decode the signal, and installed Orb 2.0(www.orb.com), these are all you need, and you must have, and of course a wireless internet router. I just got it working for a few days and I can tell you the result is excellent. Now I put a magic tape on the back of the hard cover of my old WSOD left over and stick it on the wall of my kitchen, bedroom, bathroom or any place in my house and never miss a show again. I haven't have a chance to try it outside my house yet, I will try it out this weekend if I can find a good WIFI signal somewhere.
