V+ Box should be Widescreen & RGB and then on your TV set it is switching between Widescreen and 4:3 depending on whether the program you change to is in widescreen. On your TV remote, there should be a button saying either WIDE, 16:9 or 4:3/16:9. When your TV changes to 4:3 automatically, you need to press that button until it is on Wide, or use the picture menu that you have stated the options available for above.
