I'd planned to upgrade from my 722/612/612 setup to a Hopper w Sling, Hopper without Sling, and a Joey. I thought I'd seen people get that install in the past. But I just saw a post in another sub-forum saying Dish will not authorize two Hoppers unless you also get two Joeys. Did I read that correctly? I need the flexibility of two Hoppers, but I only have 3 TVs, so 2 Hoppers and 2 Joeys makes no sense for me. Looking for some guidance! Thanks.
