But what if the two peanuts are identical? There's a lot of overlap
of the same files. It is definitely possible to fit "more" than the
specified capacity of a disc. In fact, there's been an all in one
(AIO) edition of Vista since 11/11/06. It has every edition from
Starter to Ultimate, N, x86 and x64, all on one disc. The ISO is
4,651,550,720 bytes, which fits just fine on a standard 4.7GB DVD
disc. Yes, it's an unoffical "scene" release, but Vista is mostly
useless unless you have a valid Product Key.

As to why MS didn't package it all on one disc: too confusing to
endusers. Most users aren't aware of the challenges of x64, so they
make you take an extra step to install it.
