Problem to display internet video from ie browser

I am running Windows XP with Internet Explorer 7 and cox cable. And i have windows media player 11 and it seems a to work okay when running video.
But the problem when running the embedded videos on MSN & FOX web site. I tried changing security settings, active-x controls and disabling anti-virus, My Flash Player is up to date, still can not see the display image and only voice out.
Need help to solve this problem.
