H.264 MP4 Scrubber Problem

Question

I am trying to make a custom H.264 video player. I can get
the video to load and play and all that but i cannot get the
scrubber bar to work. I tried using the onMetaData function but i
dont think it is even running because i get no trace.
Is there any way to get the total duration of the MP4 video?
[code]
//Video Loading Controls
var fileName:String = "test";
var nc:NetConnection = new NetConnection();
var ns:NetStream;
nc.onStatus = function(info){
trace(info.code);
if(info.code == "NetConnection.Connect.Success"){
playVideo();
function playVideo(){
ns = new NetStream(nc);
videoObject.attachVideo(ns);
ns.setBufferTime(1);
ns.play("MP4:" + fileName + ".f4v");
controlBar_mc.playPause_mc.got oAndStop("play");
//connects the stream
nc.connect("rtmp://137.99.136.55 /sumone4life/videos");
//Media Controls
//Play Pause
controlBar_mc.playPause_mc.onRollOver = function()
if(this._currentframe == 1)this.gotoAndStop("pauseOver");
else this.gotoAndStop("playOver");
controlBar_mc.playPause_mc.onRollOut =
controlBar_mc.playPause_mc.onReleaseOutside = function()
if(this._currentframe == 10)this.gotoAndStop("pause");
else this.gotoAndStop("play");
controlBar_mc.playPause_mc.onRelease = function(){
if(this._currentframe == 10)
this.gotoAndStop('playOver');
ns.pause();
else
this.gotoAndStop('pauseOver');
ns.pause();
//Rewind
controlBar_mc.rewindButton.onRelease = function(){
ns.seek(0);
//loadbar controls
var videoInterval = setInterval(videoStatus, 100);
var amountLoaded:Number;
var videoDuration:Number;
ns.onMetaData = function(obj){
trace("We are in metadata");
videoDuration = obj.duration;
function videoStatus(){
amountLoaded = ns.bytesLoaded / ns.bytesTotal;
controlBar_mc.loader_mc.loadBa r_mc._width = amountLoaded *
502;
trace("ns.time: " + ns.time + " videoDuration: " +
videoDuration);
controlBar_mc.loader_mc.scrub_ mc._x = ns.time /
videoDuration * 502;
[/code]
P.S. I never get the trace("we are in metadata"); so i figure
that that part of program is not even running. I have also tried
ns["onMetaData"].
I have Flash CS4 and Media Server 3.0 using AS2 if that makes
any difference.

Thanks for your input.
Actually iMovie HD 6.0.3 supports and gives you the option to create a project in several formats besides DV including MPEG-4 and HD. ( Don't know if the newest mp4 is supported). From HELP:
"iMovie HD supports importing video in common formats, such as standard definition and widescreen formats (NTSC and PAL), MPEG-4, and clips from Apple's iSight camera."
My daughter's camera is an older Sony:
Sony DCR-DVD108
Format
MPEG2
It doesn't have a Firewire or USB output, just composite video AV out which is why I have to use Elgato EyeTV to import with my setup. I usually export the EyeTV recording as DV for import into iMovie HD 6.0.3. The video is not great to start (MPEG 2) but turns to mush when exported from iMovie as anything less than full quality as a QT.MOV.
Exporting from iMovie as an mp4 ( expert settings) for web, email or download use always looks better than a comparable QT.mov.
I got away with importing from EyeTV as mp4 and editing in iMovie but not the h.264 to mp4 combo.
What combo do you suggest if I am importing "Best Quality" video from the camera (MPEG 2) into EyeTV for export to desktop for iMovie HD6?
