I can understand that you may have 11 devices for viewing in the home. I just can't imagine 11 simultaneous recordings/viewers. (Or 9, for that matter.)read post #1
i use 11 now.
Do bear in mind that the Hopper only uses 1 tuner for the 4 major broadcast networks, ABC, CBS, Fox, and NBC. So, if those make up 4 of your simultaneous recordings, it reduces the number of tuners required.
