[[Tutorial] Build Windows Vista SP1 x86 DVD using vLite]

Any idea how I do it? And will it save a lot of space?

[Do I need Vista use vlite?]

Do I have to install vista to be able to run vlite and make a stripped down version of it? I have tried vlite on two different xp pc's (32 and 64bit) with the newest .net package and they still both crashes and gives me warnings.

Is it possible to remove all other version than Ultimate? I won't be using them anyway.
