Widescreen Letterbox preserves the 16 x 9 aspect ratio of the original theater
version, but the image is placed in a 4 x 3 space, so black bars are displayed
at the top and bottom of the image. Enhanced Widescreen also preserves the

repeatedly until the image is sharp and free of streaks.

Auto Image off and on again. If the image is still bad, try adjusting the
tracking manually:
