I'm a little confused about the last two posts. I been following X0 since the beginning and I understand the straight preservation vs. cleaned up version. What I don't understand is why anyone would want garbage mats left in the straight preservation version? If you are fixing the starfields, fixing the color, etc. why would the garbage mats be left intact? They are not an intended visual artifact of Lucas' or anyone elses doing. They are quite possibly the most visually distracting part of these films, and it takes no subjective judgment to decide how to fix them. They are either on or off. It's not like cleaning up laser blasts because you feel that the surrounding glow is to intense, that stuff is clearly subjective. From a common sense perspective, cleaning up those garbage mats is no different than restoring the starfields. I hope the criteria for alteration within the straight preservation version does not stop before the garbage mats are fixed, that would be a shame.
