Looping movie clips

i have an external video that i have placed in a movie clip. its to be used as a flash banner for a website.

my problem is the video plays once and stops… i have no stop code and i have tried a few different actions to make it play. even a simple one like gotoAndPlay (1); etc.

i’m using CS4. i’ve tried using action script 2.0 & 3.0 but no luck… as well as building script on the movie clip, on a frame and its own layer.
