I have a Sky HD box connected to a Hyundai A321 lcd tv by a HDMI cable and a freeview box connected by scart. The picture size using the freeview box is correct but when watching Sky, in wide mode the picture is full height with the sides missing. When I put the telly in 4.3 mode, the picture squashes up at the sides. The problem is most noticeable when a widescreen film is recorded on the Sky box and then played back
