Hey…  
I’m trying to do something in AS3 and failing!!!  
I have an Instance of the FLVPlayer on the stage called ‘video’  
and when its buffering …

video.buffering = true;

I want to display a movie clip

buffering\_mc.visible = true;

does anyone know how i can use addEventListener statement to listen for the value of video.buffering changing??  
Or should i loop an ‘If else’ statement???

Any help would be awesome!! Thanks
