I just hooked up a new slimline dish with the latest HD pvr receiver from directv i am getting very strong signals from 101 sat in high 90,s but i get nothing from the 103 sat which carries the HD signal, i have a straight connection from the dish to the receiver any ideas what can be causing this issue, i assume the dish is tweaked properly or i would be in the hi 90's, i have both B-bands in the lines and tried swapping them from tuner 1 to tuner 2 and reset the receiver 2x's already ...could it be the new rg6 cable i used? any ideas?? thanks for all help in advance
