I have three receivers on my direct TV system. I am looking for answers as to why I get pixelization on 2 of the receivers but not on the third. This happens when the weather is not all that bad. Mostly after it has rained. I only lose some channels not all. I am not sure if they are odd or even. And some channels only have screen freeze. As an example CNN will have screen freeze while BTN will be pixilated and will not stabilize. If there is any one who knows what might be causing these problems I look forward to hearing from you.
