I have 7 TVs Using a 922 2 722's and 2 211's I am wanting to upgrade to the Wally w/EHDs to get around the DVR fees. I have all ready paid the one time 40$ EHD fee. I own the 922 but don't really care about the 722's or 211's The phone rep said Wally's wont work with a 922 but would with the 722's? Because the 922 was older than the 722's lol. I told him to send 2 Wallys to replace the 211's to start. Anyone else have a 922 and Wally Combo? BTW will be using .2 EA dish's using three dish's with RV's . Would a DPP 44 and two dish's give me any issues if I went that route?
