I really would love to be able to control the youtube player flvplayback 
component with actionscript.  the only thing I need to do is tell it to 
stop plying. heres my app: http://www.sajencorona.com/indexyoutube.html 
(click the videos link)

It works except for the fact that the video keeps playing when I try to 
unload the video. I think the problem is that i cannot unload the video 
once it begins loading. 

What I ended up doing is creating a separate clip for each video and 
hiding/showing them with actionscript.  The only problem is I need to stop 
the video when I hide it.

I can't do it without knowing the flvplayback instance.

some flash API's would be REALLY cool!!!!
