Ok, It has a big direct tv dish outside in the yard, a small dish and big T looking antenea on the roof which is OTA. So basically I need a HD tuner for it to connect to my tv. Does OTA only give local channels in HD only, or is it both HD and SD locals? Or is it just like a normal antenea but when a show is in HD it will go from SD to HD? By the way, should I use component or DVI-D cable from the tuner to the tv? It already has what it looks like coax cable from the wall which I'm assuming goes to the tuner box. By the way, if I decide to get direct tv HD receiver, would I still need the HD tuner also or is that part of the receiver? I'll try to take some pics today in case anyone wants to know what my antenea looks like.
