Here are the results from my 7 satellite screens. 1. How would I have such great numbers on most but terrible numbers on a few? 2. How would I have great numbers AND terrible numbers on a single satellite? 3. What is the difference between a 0 and N/A on a satellite? 4. Why is it that I can lose my HD local channels but still get the same channel if I tune it to the SD version of it? Thanks in advance for any help!
