I run 6 tvs from a 622 and a 722. 4 tvs have access to their own tuners( 2hd tuners and 2 sd). The other 2 tvs must share the sd tuners. They do have access to OTA and a DVR. So all 6 tvs can watch different programming( with restrictions) at the same time. The cost to do this is $17 (2nd receiver with dvr fee) and $6 dvr fee for $23.I will need 2 hoppers and 4 Joeys to get the same with the advantage that all tvs can have their own hd tuner. From what I read above the cost would be either best case $31 ( 1st hopper and joey is free, second hopper and joey is $7 , and 2 more joeys are $14 and $10 dvr fee) or worst case $45 ( 1st hopper free then 5(hopper and 4 joeys) x $7 and $10 dvr fee). So in both cases I pay more. In the best case it is $8 more and the worst case it is $22 more. So until I buy more hd tvs I hope Dish plans to support 622s and 722s for a long time.
