I purchased a 722 DVR and had dish wire the system because I only had one HD TV which is currently TV1. I have since purchased a second HD TV which is now at the location TV2. I would like to simply move the receiver to the TV2 location and do a switch of which TV recieves the HD signal and which TV gets the Standard signal. Is this very complicated, and do I need to do anything at the dish itself to make this switch?
