I would not suggest using a dual tuner or DVR for Dish with a dome. Since the programming comes from multiple satellites and your dome can only see one at a time you are going to run into programming conflicts. I would recommend the Vip211K receiver as the best update as it will allow HD on the one TV it is connected to and their is a SD TV output which you could send to the second TV. If you must be able to watch 2 different channels on 2 different TV's at the same time I would recommend getting 2 - 211K's and using one at each TV. The second receiver will still only be able to watch programming coming from the satellite selected by the first but won't cause the issues that can arise from using a dual tuner box.
