I just placed an order for a DISH installation this coming Saturday (previously had DirecTV) and am trying to understand how Hoppers and Joeys work. Currently we have a HR-20, HR-21 and HR-24 (not a whole house system). We are a family of four (two adults-two kids). Will one Hopper and two Joeys work for us? One of the TVs will be in our master bedroom (where my wife and I normally watch) one in the family room and one in the basement (we haven't bought a TV yet for the basement). Thanks in advance!
