Preloader, movie start playing before fully loaded

Hi there
I am using this preload script
totalBytes = Math.round(getBytesTotal()/1024);
loadedBytes = Math.round(getBytesLoaded()/1024);
percentDone = Math.round((loadedBytes/totalBytes)*100);
if (_root._framesloaded>=_root._totalframes) {
gotoAndPlay(“fade”);
}

It is possible to start playing the movie BEFORE it is fully loaded? It is a large movie (1.5) because there are plenty of jpg (not my design cant do anything about it) The mc display gradually so it would not change the way it looks if it started building up the screen before the end of the loading

The delay is just to long too wait!
