My suggestion: just wait and use the September release of the non-ANH DVD for the video source (but convert it to anamorphic) then add all of the different audio tracks you want to it, I'm sure a billion other people on this site are planning to do the exact same thing, hell I know I would but I'm a complete retard at this stuff (which is why I hold everyone who has done a preservation or edit in such high esteem) so I will just pick up one of those versions when they make there way to the torrent sites!
