Yes its pretty much the same as Nlite I have used it before to make vista disks as far as I can remember you need to copy the vista disk to a folder then select that folder then download the Vista SP1 Iso for either 64bit or 32bit then select service pack integration then select make iso file this takes a few hours to do, once its done burn the iso file to a dvd then you are done. you might be better of waiting till April as SP2 is meant to be coming out.
