On a somewhat related note, I currently have a copy of the Academy Awards set, which contains three CinemaScope MGM cartoons: Touché, Pussy Cat!, Good Will to Men, and One Droopy Knight. For my own amusement, I ripped them into my computer and, through use of a video editor, formatted them into a 16:9 aspect ratio to fit my screen, and placed the opening and closing titles into a black windowbox. They look pretty interesting with their letterboxed borders cropped off...
