respected programmers,

i am trying to make a flv http progressive download mechanism.  
the mechanism involves a preloader to show when the buffer is refilling.

My code is like this:

if(infoObject.code.toString()==‘NetStream.Buffer.E mpty’)  
{  
my\_video.\_alpha=30;  
var ldr:MovieClip=\_root.attachMovie(“loader”,“loader”, 0);  
ldr.\_x=Stage.width/2;  
ldr.\_y=Stage.height/2;  
}  
if(infoObject.code.toString()==‘NetStream.Buffer.F ull’)  
{  
my\_video.\_alpha=100;  
\_root.loader.removeMovieClip();  
}  
if(infoObject.code.toString()==‘NetStream.Buffer.F lush’)  
{  
//stream\_ns.seek(0);  
stream\_ns.play(vidName);  
}

* * *

However i notice that , each time the buffer fills up, the stream starts playing before the loader is removed from screen. I want to to know, why this lag is there.

also how can i solve this problem , so that each time the buffer is full again, the loader should be removed first and then the stream should play.
