Hi folks. I'm a new member who is extremely non-techie. I'm considering switching from Directv to Dish. Current Directv system feeds the same Standard Definition TV signal to my multiple TVs via coax. Would like to upgrade to the Hopper 3 with wireless Joeys (for portability), but I'm wondering if I can use wireless Joeys with my perfectly good old 4:3 aspect TVs that have the red, white and yellow ports. Can the wireless Joeys function properly with these older TVs? Would I need special equipment of any kind? I only have one Smart TV capable of receiving an HD signal. Thanks!
