But 16x9 means a 1.78:1 ratio. Such an aspect ratio would fill a widescreen TV top to bottom and side-to-side. The SW films are 2:35:1, which means they are horizontally narrower than a widescreen tv, and thus would (and indeed, have) black bars at the top and bottom of the screen. Whatever the reasoning for this croping, it was not intended for completely filling a 16:9 frame, because the DVD transfer doesn't do this.
