Removing a Video Stream From The Stage

Question

what I have:
main.swf 1 frame
btns load various external.swfs
I have 3
one swf (commercial.swf)has a slideshow inside using the SlideShowPro component Not the flv player
problem: stream remains after swf is swapped out with new.
AS code  main timeline
var Xpos:Number = 0;
var Ypos:Number = 0;
var swf:MovieClip;
var loader:Loader = new Loader();
var defaultSWF:URLRequest = new URLRequest("swfs/home.swf");
loader.load(defaultSWF);
loader.x = Xpos;
loader.y = Ypos;
addChild(loader);
// Btns Universal function
function btnClick(event:MouseEvent):void {
    removeChild(loader);
    var newSWFRequest:URLRequest = new URLRequest("swfs/" + event.target.name + ".swf");
    loader.load(newSWFRequest);
    loader.x = Xpos;
    loader.y = Ypos;
    addChild(loader);
// Btn listeners
home.addEventListener(MouseEvent.CLICK, btnClick);
bio.addEventListener(MouseEvent.CLICK, btnClick);
commercial.addEventListener(MouseEvent.CLICK, btnClick);
NOW
home and bio.swf's have _mc's inside
the commercial.swf has the slideshow pro component inside
once commercial.swf is on stage after another btn is clicked the audio remains.
slide show pro is being used not an .flvPlayer
I need to know where the code to stop the stream goes in the main.swf or the swf with the slideshow component?

Answer 1

I did get somewhere, I have a few different main.swfs I used as I was experimenting. I have one that uses  UI loaders to load all the static (no videos inside) swfs to the main timeline those work fine
Also in that main.swf I have one loader being called by the loader class which also works. But I still had the stream remaining problem. I was able to add another set of event listeners that call the "unload and stop" method on the same buttons for my main navigation that call the gotoandstops to frames and they now unload the commercial.swf (which is the only swf I have using the slideshow pro component AND stop the stream as well.
Here's what I have
in main.swf
gotoAndStop("home");
btn_home.addEventListener(MouseEvent.CLICK, btn_home_click);
function btn_home_click(evt:MouseEvent):void {
    gotoAndPlay("home")
btn_bio.addEventListener(MouseEvent.CLICK, btn_bio_click);
function btn_bio_click(evt:MouseEvent):void {
    gotoAndPlay("bio")
btn_commercial.addEventListener(MouseEvent.CLICK, btn_commercial_click);
function btn_commercial_click(evt:MouseEvent):void {
    gotoAndStop(12)
// event listeners for unloads
btn_home.addEventListener("click",afterClick);
btn_bio.addEventListener("click",afterClick);
function afterClick(e:MouseEvent):void {
    ldr.unloadAndStop();
as layer of frame 12 only loader class
var ldr:Loader = new Loader();
var url:String = "commercial.swf";
var urlReq:URLRequest = new URLRequest(url);
ldr.load(urlReq);
addChild(ldr);
this method will unload and stop commercial.swf when the home_btn or bio_btn buttons are clickedI did not try this using the UI Loader
So I now will either need to use just the loader class to call all the swfs (like a variable) what I had used before and have the afterclick function in the home and bio in all the buttons (which I will add later)
I hope this helps as there has to be a solution.
thanks again for all your help by the way.
