You have done a good job on this, doubleofive. Several changes I didn't know existed, the alternate takes for example, very interesting.
I checked the '97 version for you, and I can confirm that this Alderaan shot is a 2004 alteration.
...and maybe you could use this pic for a better demonstration of this comparison and definitely change the description of it.
I like how they managed to erase a big part of the speeder in the process of "improving" this shot. ;)
