Hopefully, someone has stumbled across a solution for this. I have an HR10 and live in a smaller market. As a result, even though I pay for and receive what few HD channels I can receive through DirecTV, the HR10 and three LNB limits me to a certain range of HD channels. The smaller market means I'm not even on the radar to receive locals in HD. That, ultimately, is the issue. I've tried every type of antenna from powered to simple rabbit ears for OTA through the DVR. NBC might come in for a bit then pixelate (sp?) on me. If I turn the channel to CBS or ABC, one might be better than the other. I can manipulate the antenna somewhat, but it only affects the other channels in a negative way. Frustrating is putting it lightly. A friend said recently, "Hey, since you have cable Internet and phone, try and connect your coax feed from cable to your TV and rescan." Sure enough, I was pleasantly surprised to see a few HD locals in the 114-2, 115-1 and 116-1 range. The part I'm struggling with is trying to receive these through my HR10. I'm guessing that it's simply not possible. I've rescanned the OTA through my DVR, but no dice. The OTA channels I normally receive are 3-1, 10-1 and 12-1. Those have no signal now and the 114-2 to 116-1 range simply do not come in. Ugh. I've since reconnected the antenna to receive the OTA, but my goal is to somehow receive the locals in HD through my cable passed through my DirecTivo HR10 unit, thus resulting in no more pixelating!!! On a side note, I am receiving an HR20 unit and 5 LNB dish come Sunday. Maybe that will resolve the issue. Thanks in advance.
