Hitting stop, stop, play on most DVD players made over the last few years takes you right to the start of the movie.
Just in case battleop reads this, let me define "most" as all but 1 DVD player I have ever put a disk into play whether it be at my house, my parents, my girlfriends, or any where else over the last few years as I have not actually tried this on "most" dvd players ever made and sold throughout the world.
