BTW, hold off on circulating Ep 1 far and wide until we've figured out how to get you a corrected copy. I'll speak with Jason privately and we'll figure something out.
Hal, I see you found your answer, but I thought I'd reiterate just for good measure.
My custom audio edit is the only one on the Single-Layer version of ANH. It's a hybrid of the 1997 and 2004. The Dual-Layer version (which is making its rounds I assume outside of the regular pyramid because of the lack of ubiquitousness of DL burners) has the custom audio edit as the default, but also allows you to choose the 1997 5.1 audio, the 2004 5.1 audio, the 2004 2.0 audio and the infamous heresy mix. I've heard zero comments on this latter one so far. And you thought Lucas raped your childhood? Bah!
Ep II is up on that Spleeny place this afternoon. Rik, as always, the community owes you the greatest debt.
