When you say you can't view .wmv files in your browser any more, what exactly do you see. Is there any error messages displayed on the page, for example a message saying "You either have JavaScript turned off or an old version of Adobe's Flash Player".
Perhaps you could try
www.youtube.com/watch?v=ZTcRbx4lMgw
(a wmv clip of base jumping) and tell me what you see. Note that when the the page is first displayed the view screen area on the page may remain black for a few seconds whilst the clip is being downloaded.
