lizzie, I'm just getting caught up with your thread. And what comes to mind to me, that is, what sticks out at me, is that your polarity seems like it could be off. Is there a way you could go out to the dish and turn your lnb 90 degrees and see what happens? Mark it so you know where to put it back at, if this is not the problem? This is just an idea, it wouldn't hurt to give it a try?
Or go into "Options" 6-4-2 and look at #4 and see if it's on Standard or Rotated 90?
