I was informed by Directv that my local channels were moving to a different satellite and that a technician would need to come over and swap out my old receivers and dish for the new ones that would allow me to view my local channels. Can I connect a digital converter box and my Directv receiver together, so that I can get the local channels without having to switch out my equipment? The new equipment is high definition, but I don't want to switch all this equipment out yet. I just want to know if I can run the converter box and the satellite receiver together?
