I am currently just over a year into my two year contract under the Dish DVR Advantage promotion. I have a 622 and a 625 reciever. I now have an HD tv in the study where the 625 is but would like to have another 622 or 722. Both of these are leased and was wondering if you think Dish will trade out the 625 for another HD DVR or should I just buy one. I dont mind buying one but I dont need three recievers. Does the DVR Advantage lock you in to just one reciever or the two I recieved when I signed up? I was wanting to know the best way to go about this before Hockey season starts.
