Need HD receiver advice

[MartyB]

Hi everyone. I FINALLY got an HD tv and am trying to figure out what my best route will be to get an HD receiver. I have my Dish through AT&T, so I'm hoping that isn't going to leave me high and dry trying to upgrade. While I would like to get the DVR, I currently have the 522, so, if the least expensive route for me is going to be getting the single tuner and just moving the 522 to another room, so be it. (Not trying to be cheap, just wanting to watch my outlay of much more $$$ at this point in time.) I guess my biggest concern is whether or not I'm going to be "allowed" to even get the receiver upgrade since I'm with AT&T/Dish. Any advice/help/suggestions will be greatly appreciated!
