The Episode 1 DVD is an abomination. The only thing good about it is the documentary.

The artificial sharpening of the picture, caused edge enhancement.

These seem to me to be tweaks rather than what was probably on the DI they used to master the DVD.

I know they did not bother to go back to the film itself since a lot of the effects were done in the computer and the film was edited on a computer. That is why Lucas probably skipped the film step altogether for Episodes II and III. Since he was going for a video look in the first place if the unnatural color timing of the theatrical release and how it looked overly clean was any indicator.

He destroyed the originals to match that overbrightened and dvnr soft image. I even wonder if he did a dvnr pass on the phantom menace after the original photography was transfered to digital tape. Since in the theater i could not see any filmgrain really there at all except during the tatooine scenes.

Which if done would have been ironic since he had them oversharpen the DVD.

Sort of Like the Tantive IV blockcade runner being blueish instead of white in episode IV now but White again in revenge of the sith,lol.
