The last couple of days the wife and I have noticed that our HD channels keep getting pixelated. At first I just thought it was cloud cover, been raining and windy quit a bit lately but then the other day it was crystal clear outside and the same thing was happening. So I then decided to go outside and check up on things with the dish itself only to notice that the dish itself practically spun on the post that Directv installed. I removed the dish and wrapped some electrical tape around the top of the post and when I tightned it down it would not budge. My question is, I need to fine tune the dish now (roughly getting a reading of 80% on the 101, 110 and 119) but I'm not sure which satellite I should start with first, 101, 110 or the 119. Any help would be greatly appreciated.
