I only saw the original SW once in the theater, but I saw the HBO version literally hundreds of times- I even recorded the audio onto cassettes by propping a mic up to the TV's speaker.

In the medal ceremony scene, there's a close up shot of Luke, Leia and Han which was cropped for TV, and IIRC the HBO version cropped out Han, leaving only Luke to the left of the screen and Leia to the right. I remember seeing another TV version once (may have been the broadcast premiere on CBS) that cropped out Luke and left Leia on the left of the screen and Han to the right. The "faces" P&S VHS split the difference and cropped off half of Luke and Han's faces, rather than cropping one of them out completely.

I have the original full-page announcement for the SW premiere from the HBO directory booklet (which used to be sent to HBO subscribers) that I will scan as soon as I get my new scanner.
