We had a DVD player in our minivan but it broke, not to mention we had problems with it (who even has a DVD) and couldn't watch Netflix on it (although it had an HDMI port, there were copy protection circuits preventing us from playing Netflix!). Currently the best option is to install an iPad with shows/movies preinstalled. The kids love it and it's very stable even when the kids play with it.
