The following code is an example of how you could calculate the value for "bytes per second" and "remaining time" when loading external movies or images etc.

I will wrap this up in a class soon.

var loadTarget:MovieClip;
var loadTimer:Number;
var loadTotal:Number;
 
function loadClip(target:MovieClip, url:String):Void {
    loadTarget = target;
    loadTimer  = getTimer();
    loadTotal  = 0;
    target.loadMovie(url);
    this.onEnterFrame = updateLoadProgress;
}
 
function updateLoadProgress():Void {
    var bLoaded:Number = loadTarget.getBytesLoaded();
    var bTotal:Number  = loadTarget.getBytesTotal();
    if (bLoaded && bTotal) {
        if (bLoaded == bTotal) {
            this.onEnterFrame = null;
            onLoadComplete();
        }
        else if (getTimer() - loadTimer >= 250) {
            var bSec:Number = Math.round(bLoaded / (loadTotal / 1000));
            var tRemaining:Number = Math.round((bTotal - bLoaded) / bSec);
            onLoadProgress(bLoaded, bTotal, bSec, loadTotal, tRemaining);
            loadTimer = getTimer();
            loadTotal += 250;
        }
    }
}
 
function onLoadProgress(bLoaded:Number, bTotal:Number, bSec:Number,
                        tTotal:Number, tRemaining:Number):Void {
    trace("loaded progress: " + bLoaded + "/" + bTotal);
    trace("bytes per second (approx): " + bSec);
    trace("total time (approx): " + tTotal + " seconds");
    trace("remaining time (approx): " + tRemaining + " seconds");
    trace("");
}
 
function onLoadComplete():Void {
    trace("loaded!");
}
 
//
 
var container:MovieClip = this.createEmptyMovieClip("container", 0);
var url:String = "external.swf";
 
loadClip(container, url);
