Those look great. I have the TR47 edition and the Dr Gonzo Anamorphics, and have been ver pleased with both of them. I did a quick look, but couldnt tell.. are the MEBEJEDI DVDs anamorphic?
Also, Im not sure what other supplement are out there, but I have THX WOW! Laserdisc, and the official THX Ultimate Demo DVD. The Wow demo is on there in anamorphic and with DD 5.1 and DTS 5.1. It also includes the soundtrack feature, wich has some scenes from Episode IV using location sound. Those could make great additions to these "ultimate" sets you guys offer.
