Ten TVs. Presently two 722Ks and one 722 are connected (all modulated) to my home distribution splitter. Any TV including the primary TVs can watch any DVR they wish. There is another 722 in the kids room that is not connected (modulated) to the home splitter. However, I do have it diplexed so it can tune in to the two 722ks and the other 722 if required. I am thinking of getting three Hoppers and six Joeys if Dish allows that and attach external modulators to them for the remaining TVs.
God ble$$ you. Di$h love$ you!
