Chances are you need to get the ActiveX certificate in order to get Quicktime movies to play in your
Internet Explorer browser. The easiest way to figure out if you need this is to go to
www.quicktime.com. Watch a couple of the newest movie trailers
and Quicktime will check your settings. If you get a message saying that you need an update, click "OK". Quicktime will
download any components that it needs and set it up for you.
