Well I've just finished ANH and I have to say that I am impressed with the picture too. Its not perfect - I wasnt expecting it to be given the source and lack of treatment. But it is far better than I had believed it was going to be. Better than the LD transfers have seen, and more importantly, I now feel I never have to watch the SE mixes again. And - crucially - it hasnt been fiddled with. Obviously I'm not as 'hardcore' as some folk here (who probably dont watch the SE's on principle) - but I'm relieved.
Oh, and the sound - the sound is sooooooo much better than the woeful 2004 DVD mix
