Works perfectly for me. I agree that the one X-Wing getting hit adds to the suspense. The music still works in a sense that the rebels managed to get out of this tight situation.
I didn't notice the window thing at all myself. Didn't pause the scene though, I just watched it at normal speed 3 times and it all looked good there.
I really can't wait for this edit. I believe it may actually surpass ANH:R. And no matter what ILM dish out for the blu-ray release, there's no way there're gonna top what Ady is doing here. His versions are the new definitive editions.
