OK, I have the HDMI chord plugged into the back of the set and the HD box. But now should I take the TV antenna chord coming out of the wall and plug it directly into the TV , or plug it into the HD box. I have an extra short cable from my old analog TV that looks like it might go from the HD box into the set but I'm not sure. How should the TV antenna chord from the wall be routed? Next how do I program TV codes ( what are they talking about? ) and volume lock? Many thanks!!
