Hello Frank,
First of all - please excuse me for the omission. I missed to notice that you are using windows media player which is actually the reason why wmode is not working for your case. The windows media player is an activeX control and the browser will always display it above all other elements on the page. Unfortunately there is no solution for this problem. The only suggestion in such scenario is to use a flash player to show the movies - it behaves as expected in all major browsers and the wmode parameter controls its appearance.
