I just signed up for ATT DISH. I told them that I needed it for 3 tvs (they have it down as one dual DVR and one standard). I was just wondering if there would be a price difference for a fourth tv - like changing the extra standard receiver to a dual one. I've looked all over their website and have been unable to find anything. Just wanted to see if anyone had run into this situation before I called them up.

Thanks!
