My son's school has had the kids create accounts at Discovery Education for learning at home on the web. Part of the site includes Windows Media videos imbedded in the website. Safari doesn't have this capability on its own, so it directs you to this page: http://www.telestream.net/flip4mac-wmv/en-US/play-wmv-in-safari.htm Has anyone here had any experience with this plug-in? Is it safe? A security risk? Thanks so much!
