I Have just purchased a Denon 2805, and have all my components video running through the amp. I get a picture fine on everything, except Sky. I am using a Scart to RCA convertor, of which I have tried two different ones that I know work, and used different cables which I know work. Any ideas why I cant get a picture from Sky through my Amp at all? It's nothing to do with cables, or the convertors, could it be something to do with the Sky box itself? Even though the Scart output is ok?!?!?
