Hi, I'm getting pixelation of my TV service from both boxes, it happens at random times and doesn't appear to be channel specific. It can happen a couple of times in a minute or it can happen after 20 or 30 minutes. GU10 area. Is this something others have experienced? It all started about a week ago, funnily enough after last Thursday when the service went down for 'maintenance'. Is this anything to do with the warm weather?
