That clip looks pretty sweet. Practically though, it's hard for me to tell the difference between a quality DVD like the ANH:R DVD-9 (just watched that on a friend's gigantic TV today. He'd only seen the OT once, years ago, but was a fan of the prequels. Some people have no taste lol. He was blown away) and HD footage, so I don't mind if it can't be done for ANH:R. I don't intend to get a blu-ray player until they're as cheap and ubiquitous as DVDs are now, so I expect to be sticking with the DVD format until the entire series is Revisited :p.
That said, it's great to hear that you're going to be working in HD.
