Depends on the age of your kids.... If they're very young and don't use a computer at home without supervision then go with the DVD player (plus it's less expensive). We bought a laptop when DS was 9 and he uses it in the car for movies, computer games, etc. For us it made more sense overall than a DVD player - we "needed" a 2nd computer at home and DS, like many kids now, has very good computer skills, so we were comfortable that he wouldn't mis-use the laptop w/o direct supervision. He actually spends more time playing computer games on it than watching movies. You can get a converter for car use so battery life isn't an issue. Plug the laptop (or DVD player) in to it, then the converter plugs into an outlet in the car and you're good to go.
