I'm wondering if there is an advantage using the Hopper/Joey's on 3 TV's vs using 3 individual HD DVR 612 receivers. We don't need anything too hi-tech, just want to watch some recorded shows on HD. We presently have a Dish 612 for the family room and a 722 for the living room and bedroom but need to upgrade the bedroom to HD. Trying to decide if I should just add another 612 to the bedroom or convert the whole house to the Hopper and Joey's. Is there any better HD content in using either system?
