I got my 61.5 dish installed today for cleveland locals.  Flipping through channels, I noticed a replay of a football game on Big 10 Network.  The PQ was unbelievably bad...everytime there was a play, it looked like the game was being played under strobe lights.  I did a point dish and noticed I was getting signal for Big10 from 61.5.  Is there any way that I can change some setting to make my channels come from 129, and if I did that, would it make a difference?
