I will be geting a second dish for 61.5 and was thinking how much more hd will be on this 61.5 satellite. Will things change when they go mpeg-4. Also when they add more new satellites will they move them to the 110 or 119 location and will this make my new 61.5 dish useless. Could the two dishes also be the same as one superdish down the line where i would not need any more dishes. Thanks for your thoughts.
