Ah, thanks. You did make a reference to the 'progressive' setting in your first post, but I guess that's just a remnant from a different tutorial...
I missed the point about Rejig - great, I'll try that! It would have been nice to put together my own author/menus for this, but since there's nothing new I can add to the ESB project (at least, no mythic alternative soundtracks in the same vein as Star Wars) it doesn't really seem worth it.
