Hallo Sven!
Folgenden Satz habe ich in einer Doku bei MS gefunden.
Dokus zum Mediaplayer und Windows Media Encoder 9 Series
• URLs. When inserted into a stream, the user's default browser opens and the requested URL loads into the browser. If you have embedded the player within a browser, the requested URL replaces the player, and users cannot view the rest of the stream. You can get around this either by displaying the requested URL in a separate frame in the same browser instance or by opening an additional instance of the browser.
Nur damit der Eintrag vielleicht bei erneuten Suchen Sinn macht.
Schönen Gruß
