I do not yet have Dish, but am familiar with cable and Directv. I see in the forum that a 622 receiver can control 2 TVs. Probably a dumb question, but can someone explain how this is done without a second box in the other room? Perhaps a Rube Goldberg series of mirrors out of the bedroom, down the hall and focused on the 622? Also, does this mean only one phone jack is needed?
