video scavenger hunt with smart phones?

http://androidforums.com – My friends and I are having a big video scavenger hunt using smart phones. We'll divide up into teams and go out for several hours, then come back and watch every team's videos. I know there's a cable from the apple store that allows you to connect your iphone to a TV to play the videos, but is there such a cable for android phones? Because there will be multiple phones, and they'll be other people's I can't require them to download any apps. And each team will have a ton of videos to play so they must be quick and easily accessible. Thanks! (General)
