I really like the Dish DVRs with integrated ATSC tuners. My brother has the 625 which I understand is an SD only DVR with no ATSC tuner integration. Also he is limited to 2 tuners. Do the 722 and 622 have 3 tuners plus the ATSC tuner? Anyways. I would like 1 HD-DVR to operate 2 HDTVs. I would like to be able to watch 2 different channels and record a 3rd at the same time....is that possible? Im thinking DVR Advantage(AT200) with HD Essentials is the way to go, with the 722 or 622 HD DVR. Are there any special promotions are discounts available to new subscribers? Help, newbie needs advice.
