If You Could Take Just One DVD Set On A Space Voyage, What Would It Be?

Say you're going to another planet, and it's going to take months or even years to get there. You can only bring one DVD set (or there's only room in the spaceship's computer for one set of video files.) What do you bring? And why?

Please include a picture (or cover) or clip for your chosen box set. And please mention the name, and why you'd want to be able to watch it over and over again as you journey to another world. Thanks!
