ActionScript 1/2 :: Make The Buffer Invisible Until MouseOver In A Flv Player?

I am adding a swf to my website with a streaming flv player and I would like to make the buffer mc invisible until the invisible button covering the video player is moused over. I would like the net stream to begin when the page loads, but for the video to begin when the player is moused-over, and then pause when moused-off, right now the buffer is showing on page load and the animation is really distracting.

This is the code I am working with:

var nc:NetConnection = new NetConnection();
nc.connect("rtmp://rtmphost.com/banner/");
var ns:NetStream = new NetStream(nc);
