My picture keeps pixelating and cutting out! - DirecTV

#1
It seems when I'm watching AMC, namely, Fear The Walking Dead or The Walking Dead my picture freezes up and stutters and pixelates.
Its just frustrating because resetting my reciever only helps for a few minutes. My dish itself isn't covered in anything so I don't understand why this is happening.
Has anyone had this issue and how have you resolved it?
