What the? If they're doing it as DVD-18, not only is it a flipper, but it would most likely include the 4hr doco, as the DVD-18 format is massive in storage space. However, if they can do that - why don't they just do it as a 2-disc set? DVD-18's aren't as common and I would think would cost more to produce, and they break easier than standard DVD-9s. THey also are reported to have a lot of problems whilst playing. This is a bizarre piece of info.
