attachSound and attachMovie problem

Hi!

i m working on sound and movieclips and using method

mySound = new Sound();
mySound.attachSound(“some sound from library”);
mySound.start();
//
myHolderMc.attachMovie(“some mc from library”, “newName”, 10);

all is going well … but problem is all the object in library that i m using with actionscript are exproted in first frame of the movie resulting in a slow runing of movie.

i want to distributes only the soundclips into saprate files keeping all the actionscript into main file and to load these soundclips on runtime from other file and run them by main file’s script

anybody tell me the solution please
