Just purchase DVD Xcopy Express, this will copy just the movie, but really, what else do you need? It fits a 9 to a 5 DVDR, just one disc. They're also coming out with DVD Xcopy Express GOLD version which will copy everything including menus and special features to one disc.

It's very simple to use too, a monkey could make a backup copy... no need to do anything manually at all. It's just 2 clicks of the mouse and there you go.
