I've just bought a Samsung Series 5 "32 to add to my Sky Plus box and Sony Dav X1 dvd system. They are all hooked up by good quality scart leads, but the picture on my TV from Sky is awful - not what I was expecting. The dvd picture is good though. Any advice on what cables to use to remedy the poor Sky picture? Also, should I use a HDMI cable to link the DAV X1 to the TV even though it's not Blu-ray? Any advice on optimising my system appreciated!
