var i = 0;

onEnterFrame = function () {
i ++; 
if (i == 100)
{
fadeout (); 
}
}

you can use setInterval to control how long you would like the movie to stay at the current frame and tell it to play again at a specific count.

var counter = 0;
function callback(arg) {
counter++

if(counter == 20){
play();
counter = 0;
clearInterval(this);
}else{
stop()
}
}

setInterval( callback, 1000 );

If you use the onEnterframe function discussed in the previous post be sure to use delete onEnterframe once your condition has been met.

// Stop the movie
stop();

// How many seconds until we continue?
var nSeconds:Number = 5;

// Function which resumes playback
function continueMovie():Void{
     play();
}

// Set the interval
var iNum:Number = setInterval(continueMovie, nSeconds*1000);
