Support for 16:9 Display size. Now there is multiple modes for 4:3 screen, but what about 16:9 display? If I choose LetterBox mode for Widescreen (20:9) movie, the black bars are added to set the correct aspect ratio, but only on 4:3 screen. If I choose this mode on 16:9 TV the picture doesn't have correct aspect ratio. As there are more PAN&SCAN modes, there could also be more LetterBox modes which would work on 16:9 TV.
