I am thinking about upgrading to a Hopper and one Joey from a 722 and would like to know how Dish Anywhere works with the Hopper. Is it like the 722 where it uses the tv 2 feed to operate. In other words, with a Hopper and Joey would i loose being able to watch the Joey feed if someone in another room logged on to Dish Anywhere on an IPad or can you watch three programs at once?
