Received the Homeworx and got it all set up. Works like a charm. Get about 15 channels from my rooftop antenna in HD. Remote works just fine, quickly changes channel. Comes up with what is currently on screen, and what is coming up next in a box at the bottom for a few seconds. I never record anything, so won't be trying out the PVR functions, but happy with the purchase so far.
One thing of note; the Homeworx is incredibly cheap feeling. It weighs almost nothing. The box feels like thin cheap plastic, I was actually nervous handling it because it feels so flimsy. I was so surprised at the lack of weight that I had my son come over and hold it. I am sure there is a single green board inside, and that's it. I have it sitting on top of an Xbox360 (not on the vent), but I think I will move it to where it won't come in contact with anything else. Other than that, it does actually work and the picture is clear.
