Get 2 ehd's. One for each receiver. There is no additional fees for the 722, but it will cost $40 to activate the 211, but believe me it's worth it. I had a spare 400 gb drive laying around for several years. Finally hooked it up to the 211. Gives you all the freeze, back and forward features of a dvr and if you have ota reception you can record a Dish signal and an ota signal at the same time.
ok,ty
