Movie too big? Create a pre-loader using if then else capability of actionscript!
Example: Create a simple animation that lasts 20 frames. On frame 21 add an action script that checks to see if the rest of your movie is completely loaded. If your movie uses 500 frames, your script would look like this

if (_framesloaded=500) {

gotoAndPlay ("Scene1","22");}
else {
gotoAndPlay ("Scene1","1"); }

Newground's Flash Help has a preloader you can use for your site if you don' t like the one you created!
