Like I always say, the garbage mates shouldn't be there because they are a mistake created by the video transfer, not the original cinematography.

I tend to agree. There is a difference between preserving the film versus preserving the video. I don't ever remember seeing boxes around the fighters in the theater. I'm guessing some people did, but I think that they shouldn't have been visible in a properly configured projection. Just because early video transfers exposed some things that wouldn't have been seen in the theater, doesn't mean that those artifacts are worth preserving on later, better home videos.

However, the vaseline under the speeder was present in the projection, and I find it interesting that they came up with that solution. It was there intentionally and it was a creative way to deal with a difficult problem, and nothing for Lucas to be embarrassed about. I never knew it was a "problem" until we were told in 1997 that it was a problem.
