The only thing I've ever run across is a very short clip out on the web in RealPlayer format. It does show the entire recreated opening scene from Star Wars, which made me happy to see it again. Unfortunately, I can't seem to find the link now.

Sad that so many IMAX films have been released to DVD, yet this one has just disappeared. It would be a big seller if they would only put it out. I'd even go see it at the IMAX theater again if they showed it.

I recall it also had desert scenes shot from a bouncing dune buggy as they were going out to film the new shots for the Star Wars Special Edition featuring the stormtrooper patrol.
