When letterbox images are setup for a 4:3 aspect ratio screen, the black at the top and
bottom of the image are the result of the difference between the original aspect ratio
of the movie (1.85:1) and the 4:3 (1.33:1) aspect ratio of the display.

DVD Disks

Most available DVD disks are not formatted in a 16:9 aspect ratio. They are
generally 1.85 or 2.35. When viewed on a 16:9 display, they appear in a letterbox
format (although the black area is slightly smaller than the 4:3 letterbox).
To display a full screen image, the DVD disk must be formatted as HDTV (16:9
aspect ratio).
Camcorders
The normal mode for camcorders is a 4:3 aspect ratio. Most new models have a wide
mode setting for 16:9.
