I am fighting with Dish because I wanted two HDTV's with DVR and they gave me one 722k. When I learned that what I got was one HDTV and one SDTV sharing a DVR I was upset. Dish will not fix this, I continue to fight them. My question is this; can I add a 211k with an EHD to my second TV? If I do this will I have HDTV on my second TV with a DVR and still be able to access my 722k DVR? I'm thinking of just using both to have a dual tuner like DVR and have HD. Does any of this make sense, and will it work?
