I just got the WookieeGroomer set and it really shows up how many changes were made for the 2004 DVDs. But it also shows how much more detail you can see in the image, which is not available from the LD. Now I am of the opinion that using the DVDs is a non-starter as far as preservation goes, as every frame has been altered by grotesque over-saturation, colour "correction" and contrast boosting (even where there aren't any new CGI elements) in a way that cannot be undone. However, aren't there huge swathes of the 1997 Special Edition wherein the picture is identical to the original release (all except the scenes with new CGI elements)? Would it be possible to use one of the DVB recordings like those used for the GKar or "TB" DVD sets for the majority of the picture, reverting to X0 LD caps for scenes which were altered in '97?
