Unloadclip does not unload everything

Question

I create a menu system to load an external SWF movie by using
loadclip.
no problem so far, the swf movie load.
but when I use unloadclip to unload the external SWF movie,
the movie dissapear which it is good but....
the external SWF movie has a setinterval running, if I unload
before it finish, it still running in the background even I use the
unloadclip to unload it.
I thought the unloadclip show remove everything from that
external SWF movie even thought there is a setinterval running.
I am not sure if this is a bug where the unloadclip does not
unload everything.

Answer 1

Hmmm,
well, for the application that I am doing putting up a
cleanUP()function in the external SWF(movie1.fla) will not work.
To define in the parent(main Menu) is better but how do I do
it. see the code here, there are 2 FLA file, one for the Menu and
the other is for the Movie file
also, I am unsing unloadMovie(); to unload it. and not
unloadClip;
I don't know how to set a intervalID on the movie1.fla and
then return that value to the main Menu program so I could kill it.
as you can see in the movie1.fla, I put
"trace(bar_mc.scrub._x + " this is the videoInterval ID=
"+videoInterval);" so when I unload it from the main Menu, it keep
running for testing.
Menu program
var mcLoader:MovieClipLoader=new MovieClipLoader();
load_btn.onRelease=function(){
mcLoader.loadClip("movie1.swf", dummy_mc);
unload_btn.onRelease=function(){
dummy_mc.unloadMovie();
Movie file(movie1.fla)
//Create video stream
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
tstooge.attachVideo(ns);
ns.play("video/Microsoft IPOD.flv");
play_btn.onRelease = function() {
ns.pause();
rewind_btn.onRelease = function() {
ns.seek(0);
var videoInterval = setInterval(videoStatus,100);
var amountLoaded:Number;
var maxWidth:Number = 241;
var duration:Number = 175;
function videoStatus() {
amountLoaded = ns.bytesLoaded/ns.bytesTotal;
bar_mc.progress._width = maxWidth * amountLoaded;
bar_mc.scrub._x = ns.time / duration * maxWidth;
trace(bar_mc.scrub._x + " this is the videoInterval ID=
"+videoInterval);
if(bar_mc.scrub._x > 241){
clearInterval(videoInterval);
//scrubber code
var scrubberInterval;
bar_mc.scrub.onPress = function()
clearInterval(videoInterval);
scrubberInterval = setInterval(scrubIt,10);
this.startDrag(false, 0 , this._y, maxWidth, this._y);
bar_mc.scrub.onRelease = bar_mc.scrub.onReleaseOutside =
function()
clearInterval(scrubberInterval);
videoInterval = setInterval(videoStatus,100);
this.stopDrag();
function scrubIt()
ns.seek(Math.floor(bar_mc.scrub._x / maxWidth * duration));
