I want to burn DVD movies. For Christmas I received a new DVD burner and a new 80 Gig hard drive. My current boot drive with XP is a 28 Gig drive. Should I install XP on the new 80 Gig drive and store my DVD files on it to burn to DVD or can I just use my 28 Gig as my boot drive, store my DVD files on the 80 Gig as slave drive and burn from it to the DVD? Which is most efficient?
