Watching the '06 GOUT ANH disc, I noticed a considerable amount of grain in alot of the scenes.
Especially the Tantive attack, and on Tatooine.
I don't have a LD player anymore, so I can't put the Faces LD's I have in, for direct comparison.
But I don't remember the LD's having that much grain.
Is it simply because the DVD reveals the imperfections of the transfer?
I had read on one of the other SW forums that some people think that Lucas intentionally "grained" up the GOUT DVD's in order to further detract their quality from the 2004 SE DVD's.
That seems silly to me, but with Lucas I never rule out anything.
