Chris, not sure if it's relevant but I also seem to have a few dodgy channels atm.. So it's likely to be a sat issue (either low power or a sat has creeped outside or towards the edge of the box) than a local issue.. That's the thing in that if the dish was set up when for example the sat was in one corner of the virtual box then months down the line it might have creeped over to the oppisite corner
