AIR 3.2 StageWebView complete event not working on iPad2

This is still bugging me. Whilst the cut down example did indeed work, when I try this for a video, it does not work. In the following example, I can hear the video playing but I cannot see it. The onVideoLoadComplete function is not being called.

Any ideas why this would work when loading a website but not when loading a video. If I put the  webView.stage = this.stage; where I have commented out, the video displays correctly however I need to display and remove things from my app once the video has completed loading. Is this a bug or am I missing something here? Perhaps there is no way to detect when a video has completed loading? I am packaging with Flash CS5.5 and AIR 3.2

import flash.geom.Rectangle;

import flash.media.StageWebView;

import flash.filesystem.File;

var webView:StageWebView = new StageWebView();

var path:String = new File(new File("app:/video.mp4").nativePath).url;

// webView.stage = this.stage;

webView = new StageWebView();

webView.viewPort = new Rectangle(100, 100, 400, 300);

webView.addEventListener(Event.COMPLETE,onVideoLoadComplete);

webView.loadURL(path);

function onVideoLoadComplete(e:Event):void {

          debugTxt.text = "video load complete"; 

          webView.stage = this.stage;

}
