how to broadcast windows media player video into justin.tv

[fcortes]

I have a channel in justin tv and I'm currently using superwebcam as my video capture device combined with jtv broadcaster. (i can't use FME in this computer for some odd reason). what I want to do is use windows media player as my video capture device so I can use the random function from wmp (the one from from superwebcam is pretty lousy), is there any add on or software that can make my wmp a video capture device so I can use it with justin tv broadcaster?

thanks
