game card

Hello! You know how games shows who worked on the game before you actually play the game? I would like to do that! I have the video and it's the right dimensions but i can't get it to play. i tried the image launch = Movie(play="opencard.mp4", pos=(10, 10), anchor=(0, 0))

But that did'nt work, then i tried just saying play movie "opencard.mp4" and that froze up the main menu for five seconds. Help please.
