Can someone tell me how to save a dvd movie to my hard drive, so that I can go back later and watch it? I am wanting to save a couple of movies on my laptop, so that I may watch them while traveling. I am told that by saving to the hard drive, the battery will not run down as fast. I tried saving a movie, only to find that the computer could not find a program to run the fill. Is this just a matter of the format that I am saving the file in? Any help would be appreciated!!!
