What Jim5506 proposed is precisely what I ended up doing. I'm also a new Dish customer. I have 4 HDTVs, and Dish would only lease me up to 3 receivers, consistent with their new policy. I originally ordered two solo HD DVRs (612, I believe) and one HD receiver (211/211k). After more research, I decided to change my primary receiver to the 722k Duo for the newer platform and bigger internal drive, since there is no additional fee. I also realized that I didn't really need two sat tuners on the other TVs, so I dropped the other two receivers to the 211 with the intent of doing the DVR conversion. I purchased a third 211k, activated the DVR, hooked up a DB4 to all 4 receivers for OTA (OTA module purchased for 722k). I love the setup now.
