Creating a digital copy of a DVD movie

Off the top of my head I think you could try to copy the ISO for all your DVD movies and store them on your hard drives. Then mount the ones you want to watch to a virtual drive with something like Daemon Tools. The only downside to this that the ISO images will be larger files compared to just ripping the movie from the DVD and encoding it. But you do get all the bonus features, scene selections and all that.
