It's actually very good, although not perfect DVD quality, it comes pretty darn close. I watched it last night on my crappy LCD laptop screen. The sound is also pretty good (I was using headphones, though) and it had lots of details I missed. It was weird seeing the Original version because I've only seen it maybe one time (when I was extremely small), my childhood was really with rthe 97 Special Editions.
On that note, I'm heavily considering doing my own set (*gasp*) to recreate the 97 SE (except for the bits that mess with characters and drama), as that's from my childhood. I still have my dusty ol Pan and Scan (eww) VHS set of it, too. I have to do some reading about DD 5.1 and learn how it works first, plus read about some things, collect a list of sources (there's no need to recolour sabers; I'll use what others have done if they'll let me).
I figure it's worth it since no one has done much with the 97 SEs and I'd love to see the version from my childhood in glorious 5.1, anamorphic, DVD quality. From what I've read, the 2004 DVDs are just edited to fit the prequels, which I didn't even really like. Alas, though, I'll have to pick up a copy because it's required source material.
I love messing around with video so this ought to be a learning experience... and fun! *runs off to read stuff*
