I'm going to make a re-mux of EditDriod's ROTJ soundtrack + menus w/ TR47's ROTJ video + PCM audio. I've only got 75% of the TR47 ROTJ disc, but I think I figured out how to work IFOEdit . Talk about a serious lack of user interface...
[EDIT] Actually, come to think of it, there might not be enough space on the DVD for the PCM audio and the sound track. I might have to nuke the DVD_ROM folder, but that sould still be cool...[/EDIT]
