Plasma set to 16:9, sky box set to 16:9 RGB...... while watching BBC1 sports personality of the year I was getting black bars on the sides for the studio shots but when a graphic was cut up it was full screen. Looking at the news the heads of the presenters are long. Any idea? watching reality TV it looked 16:9...is there a broadcast problem at source? any help greatly appreciated.... watching analogue because of this!
