Topic: Video clip will not play automatically

I have searched the forums but don't see this topic...I have a recording done with Presenter that includes PowerPoint, audio and one slide of video.  If you manually arrow over (forward or backwards) the video plays perfectly.  BUT, if you let the slides run on their own, the video does not start and the whole presentation stalls out at this point.  Any suggestions?  I am going to try to update the slide transitions, but don't know what else to try.
