Well, I just got done doing a side-by-side split-scren comparison of my "Faces" and DefCol disks (the scene where Luke leaves Dagobah) and I am very surprised. The DefCol is much cleaner, with more contrast, a deeper black level, and much better detail. I may have to go back and redo ANH sooner than I thought. Good thing I haven't started compiling my ESB DVD yet.

Although, I'm a little sad, because my DefCol of ROTJ has some speckles here and there, which are most noticeable in the darker scenes (i.e. end of ROTJ, which I love.) Oh well.
