Hi Guys,

I have a strange issue with the FLV files i imported to my site.  
These FLVs were imported with Alpha channels.  
In my site there is a button, that when its pressed for each FLV it starts playing.

The Problem is after its been playing for awhile there is a strange Noise at the background that starts appearing slowly. (Please see attached file).

The only code i have on each FLV is for transparety and a Loop (Plaese see below):

Anyone knows maybe what is this thing? i never saw this before.

Thanks For your help

[COLOR=red]onClipEvent (load) {  
this.\_alpha = 0;  
this.dir = -1;  
}  
onClipEvent (enterFrame) {  
if (Math.round(this.\_alpha) == 0 || Math.round(this.\_alpha) == 100) {  
this.dir _= -1;// change the direction of the fade  
}  
this.\_alpha += 5_this.dir;

}

on (complete) {  
this.autoRewind = true;  
this.play();  
}[/COLOR]
