Preload SWF Levels into Main Movie

Question

Hello - Can anyone suggest a reliable and efficient way to
preload several SWF movies into one Main "Container" SWF... and
show one progress bar. My problem is that I don't need all my SWF's
initially (they will be needed when the user navigates to that
page) but I would like to load them into some sort of cache for
later access. I would GREATLY appreciate any comments or
suggestions! Thank You!!
Here's what I am doing so far, but it's not working great:
On my master SWF I have the following Code in Frame 1:
stop();
//---------Function to Load New Movie--------------\\
var myMCL:MovieClipLoader = new MovieClipLoader();
var myListener
bject = new Object();
myMCL.addListener(myListener);
//---------/Preload Levels---------------//
myMCL.loadClip("Movie1.swf", 1);
myMCL.loadClip("Movie1.swf", 2);
myMCL.loadClip("Movie1.swf", 3);
myMCL.loadClip("Movie1.swf", 4);
myMCL.loadClip("Movie1.swf", 5);
myMCL.loadClip("Movie1.swf", 6);
THEN: on frame 2, I have all the movies I don't want to play
initially unload (with my thinking that they will be immediately
accessible when needed):
stop();
unloadMovieNum(1);
unloadMovieNum(2);
unloadMovieNum(3);
unloadMovieNum(4);
unloadMovieNum(5);
LAST OF ALL: I have this script in my preloader movie (to
supposedly add up all the bytes to load and show one seamless bar
for them all)
onClipEvent (enterFrame) {
// get the amount currently loaded for sum of all levels
loading = ((_root.getBytesLoaded()) +
(_level1.getBytesLoaded()) + (_level2.getBytesLoaded()) +
(_level3.getBytesLoaded()) + (_level4.getBytesLoaded()) +
(_level5.getBytesLoaded()) + (_level6.getBytesLoaded()));
// get the total needed to load for sum of all levels
total = ((_root.getBytesTotal()) + (_level1.getBytesTotal())
+ (_level2.getBytesTotal()) + (_level3.getBytesTotal()) +
(_level4.getBytesTotal()) + (_level5.getBytesTotal()) +
(_level6.getBytesTotal()));
// get percent variable by dividing amount still loading by
the total amount needed to load
percent -= (percent-((loading/total)*100))*.25;
// make the percent an integer (no decimal)
per = int(percent);
// display that integer with percent sign to make variable
percentage load in dynamic text box
percentage = per+"%";
//move movie clip slider to show percentage
tomMC._x = int(per * .01 * 230);
// if the amount loaded is great than 99 percent (i.e. it is
almost 100) then let master continue to play
if (percent > 99) {
_parent.gotoAndStop(2);

Just a thought- can i refer to the external movie through the
loading component instance name?
Still wondering if I can control the time line inside the
external movie from the main movie...
