I have two identical 622's running L713 software. One runs great but the other one has started doing weird things. When the weather is great outside, it gets that picture like when you get bad rain or wind fade, so bad it is un-watchable. To be more specific, the moving part of each picture seems to smear and pixelate horribly. When it gets really bad, the machine shuts down and reboots. I have great signal strength on this box and the other 622 shares this same dish. Any ideas. The box is 5+ years old.
