VideoDisplay not loading new video on a Mac

Question

Hi Everyone,
I am at the final stages of releasing a product to my client and if I dont get this problem fixed it may be detrimental to me getting paid, so much hair has been pulled out so far!!!
I have a created a bbc iplayer type application that downloads videos, stores them for viewing offline and plays the selected one.   Before the selected video is played, a 10 second flv containing the clients logo plays.
This works fine on a windows system but a Mac doenst like it.   The intro animation plays, but when it is finished it does not play the second video loaded into the videodisplay component.
If this works on a windows system it means there is nothing wrong with my code - right?    The  both videos exist and the player plays both so therefore the code is ok.  Is there a known problem about how the videodisplay component renders video on the Mac?
I thought one of the benefits of using something like Air was that you didnt have to worry about the operating system it resides on.
Here is a simplified version of my code below if anyone can spot why this would be.
//Called on creationComplete
protected function onComplete(evt:FlexEvent):void { launchSplash() }
protected function launchSplash():void
   //trace(">>VideoPlayerPanel:launchSplash--")
   _videoDisplay.source = "assets/Ident.flv";
   _videoDisplay.addEventListener(VideoEvent.COMPLETE,onSplashComplete)
   disablePlayercontrols()  
protected function onSplashComplete(evt:VideoEvent):void
   trace(">>VideoPlayerPanel:onSplashComplete--")
   _videoDisplay.removeEventListener(VideoEvent.COMPLETE, onSplashComplete)
   _videoDisplay.stop();
   _videoDisplay.source = null;
   _videoDisplay.close()
   Alert.show("Starting 1.5 Second Timer","onSplashComplete")
   var _pauseTimer:Timer  = new Timer(1500,1)
    _pauseTimer.addEventListener(TimerEvent.TIMER_COMPLETE, onTimerComplete)
    _pauseTimer.start()
   function onTimerComplete(event:TimerEvent):void
    trace(">>VideoPlayerPanel:onSplashComplete:onTimerComplete--")
    Alert.show("Timer Completed - Setting Video to play","onTimerComplete")
    _pauseTimer.removeEventListener(TimerEvent.TIMER_COMPLETE, onTimerComplete)
    _pauseTimer.reset()
    playSelectedVideo()
protected function playSelectedVideo():void
   trace(">>VideoPlayerPanel:playSelectedVideo--")
   Alert.show("Video Should be playing","playSelectedVideo")
   _videoDisplay.source = _vidSource;
   _videoDisplay.play()
   enablePlayercontrols()
   if(_videoData.type.toString() == "audio"){showAudioImage()}
If anyone can help me on this one I greatly appreciate it as I work on my own so have no one to look over my code...
THANKS!

Hi,  OK here is the basic code in two forms - one attached and the other one
pasted below:
The Ident video plays fine, but the video loaded in by the user does not
play on the Mac (fine on windows)
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" initialize="init()">
     <mx:Panel width="100%" height="100%" title="Video Window">
          <mx:VideoDisplay id="_vidDisplay" width="100%" height="100%" source="ident.flv" autoPlay="false" />
          <mx:ApplicationControlBar width="100%">
               <mx:TextArea height="20" width="100%" text=""/>
               <mx:Button label="Browse" click="{browseForFile(event)}" />
               <mx:Button label="Play" click="{_vidDisplay.play()}" />
          </mx:ApplicationControlBar>
     </mx:Panel>
     <mx:Script>
          <![CDATA[

                    protected var _appDir:File;
                    [Bindable]
                    protected var _vidSource:String;
                    protected function init():void
                         _vidDisplay.addEventListener(VideoEvent.COMPLETE,onSplashComplete)
                    protected function browseForFile (evt:MouseEvent):void
                         trace(">>Main:browseForFile--")
                         _appDir = File.userDirectory.resolvePath("UKA");
                         _appDir.browseForOpen("Select your video to load")
                         _appDir.addEventListener(Event.SELECT,onSelected)
                    protected function onSelected(evt:Event):void
                         trace(">>Main:onSelected--",_appDir.nativePath)
                         _vidSource = _appDir.nativePath;
                         _vidDisplay.play();
                    protected function onSplashComplete(evt:VideoEvent):void
                         trace(">>Main:onSplashComplete--", _appDir.nativePath)
                         _vidDisplay.removeEventListener(VideoEvent.COMPLETE,onSplashComplete)
                         _vidSource = _appDir.nativePath;
                         _vidDisplay.source = _vidSource;
                         _vidDisplay.play();
