Thank you for your answer. Im new to web pages, but I have been looking for silverlight solutions already. The problem is, that those examples out there, are using a static video control. For en example, a video player has an embedded start/stop button. What I need is to control this player outside of the videoplayer. So when, for an example, a user clicks on a button on the page, or the page recevies a message from a server, the video would start. This is no problem in an ordinary application, but how to do it in a web app?
