I have QuickTime, but just a bar is there with the arrows, etc, no video
I got it to work just fine....some of the clips require a fair amount ot time to load, as about fifty thousand FReepers are trying to look at them right now and the load on the system must be pretty significant..
Click on the link to the individual clip, click on the box to activate the QT control. When you see the bar at the bottom of the box that has the play button on it, just let it be for a few minutes. After a while, it should have either downloaded at which point you can click on the 'play' control, or you should see significant progress, as indicated by the dark band to the right of the Play control.
I hope that this helps :-)
