Newb here, did some research on my question but couldnt find an answer here so I apologize if the question has been asked already. Just had the 622 installed in my home, receiver connected to an HDTV via component (main TV), the RF output on the box is connected via coax to my in home cable wiring providing a signal to a 2nd TV also an HD TV. So far, I'm very happy with all the HD channels, the guide is great, DVR easy to work, etc., etc. Before the Dish install, I had the main TV connected to my old Cable HD DVR. The 2nd TV was connected directly to a Coax cable in one of the bedrooms. The 2nd TV has a built in QAM tuner so when I first brought it home, I simply connected it to the coax, the TV searched for and found a variety of HD channels that I was able to view without a problem. Now, I get no HD reception on the 2nd TV. I'm assuming that, without another box, this will not change but I'm interested in knowing why. Anyone? Thanks in advance for the help!
