I'm still struggling with NetStream concepts

Hello, me again.

In flash proffessional 8 help documents, there’s an example of making a preload flv. It is nice, a text object indicates the percentage % of movie loaded. But there’s a problem because the line:

stream_ns.play("http://www.helpexamples.com/flash/video/typing_short.flv");

shows the video while the loading bar is indicating the progress of the loading (like youtube). The effect I want is that after the loading bar reached the 100%, the movie be shown. Oh! I have an idea, what if I set the video object my_video._visible= false, while the bar has not reached the 100%?. I will try it :cap:. Any other suggestion?
Thanks friends.
