I am not sure if I am doing this right or not. When I go through and set up my box it lists three diffrent channel 2, 4, and 7's. When I go to them the picture is normal on one, the second is all dark like there is nothing found (says searching for signal), and the third is all fuzzy like the channel is not comming in clear. I got the best antenna that best buy sold so that I would be able to receive the over the air high def channels but I am not getting any. I am starting to think that the one that says searching for signal is the one tht is suppost to be the high def on, and if there is not a HD signal being sent it willl just say that. Am I right? If not, what do I need to do so that I can get my OTA channels in HD?
