I'm trying to run a video created with Microsoft PhotoStory, which uses the windows media video 9 image v2 format (WVP2).  My article includes the link {wmv}videoname{/wmv}.  The video will display, but won't play.  If I change the video to another format, such as windows media video 9, it plays fine but is much larger.  Is WVP2 supported?  If so, do I need a different tag?  I'm using AllVideos version 3.3, on Joomla 1.5.20.  I've tried both IE and FireFox as the browser, and received same results.
