I got my HD service setup today and the cable guy stated that if I wanted to use HDMI, that i would have to switch it out with the component cables whenever I wanted to watch nonhd channels. Is this right, is there a reason he would say this? I have ordered some very good HDMI cables off amazon and they should be here in a few days, so I haven't had a chance to hook them up and see for myself. Any help is appreciated. I surely don't want to go through the hassle of switching out cables just to view nonhd channels.
