- Changing of graphics during the Death Star Battle of the "aiming computer" displays
What did they change?
- they fixed the "jump cut" when 3PO and R2 are walking past the shooting stormtroopers at the beginning, when the explosion to the right is detonating
- they fixed the "jump cut" during the beginning of the movie when R2 unrolls his third leg, after Leia gave him the plans...
Are you sure you weren't watching my edition?

I had to fix both of those because the jump cut is still evident (there is no jump in the picture as a whole any more, but they didn't fix the hopping stormtroopers or the slight jump that was still left on R2 - and it wouldn't be something you could show with still pictures anyway).
There were all kinds of wobbly cuts present on my SE LDs which are almost entirely gone on the DVD.
There is still lots of film grain in the 2004SE
