Flash Video Question

Hi guys... first post, hopefully someone out there can help me solve this issue? Its been causing me alot of pain.

Ill explain my problem...

I have a button created in a movieclip which when clicked slides down another movie where a mediaDisplay componet (instance name myVideo) is housed to play an FLV. I modified the url to play the appropriate external flv video and it works fine but what I would like is to make the the contentPath/URL to the video in an xml file. That means when I modify the external xml file the video housed in the mediaDisplay component changes to the new updated video.


anybody know a method to solve this? Or point me in the right direction?

Thanks
