I got Sky+ and Toshiba DLP TV 46WM48. For some time, the TV automatically switched between 4:3 and wide screen depending on source format of channels. Actually, it wan't like that from the beginning. It used to be fixed format whether 16:9 or 4:3 as set in TV menu. Different ratio format from Sky didn't force TV to change accordingly. Then suddenly, TV started automatic switching and it lasted for several months. And then again, it went back to original behaviour - fixed ratio regardless of source format. 'Scart Control' in Sky's 'Picture Settings' is ON. Can anyone shed light on this?
