NetStream doesn't play mp4 packaged with app - but plays same file over http

Question

I'm using StageVideo to play an h264 encoded mp4 file in an iPhone app.
When I package the mp4 file with the app (in the root), the app doesn't play the video at all. When I simply change the video's location to a http location where the exact same file is located, it plays fine.
In other words, the only change I'm making is:
Packaging mp4 in root of app:
var _videoURL:String = "video_h264.mp4" ;
_nc = new NetConnection ( ) ;
_nc.connect ( null ) ;
_ns = new NetStream ( _nc ) ;
_ns.client = this ;
_ns.play ( _videoURL ) ;
_stageVideo.attachNetStream ( _ns ) ;
to
Hosting video remotely:
var _videoURL:String = "http://www.myDomain.dk/video_h264.mp4" ;
_nc = new NetConnection ( ) ;
_nc.connect ( null ) ;
_ns = new NetStream ( _nc ) ;
_ns.client = this ;
_ns.play ( _videoURL ) ;
_stageVideo.attachNetStream ( _ns ) ;
Does anyone know if there's some restriction when using NetStream that could explain this?

You can get away with just the relative path. But, do make sure you added the folder with the videos in the General tab.
Another thing to know, you may not get a StageVideoAvailabilityEvent.STAGE_VIDEO_AVAILABILITY, that may have already happened before you start looking for it. In case like that you can get remote videos to work, and local videos will sometimes work. Seems to be  amateur of timing.
The way I worked around that issue was to check the stagevideos before listening for the event. Like this:
if ( stage.stageVideos.length >= 1 ) {
  enableStageVideo();
}else{
  stage.addEventListener(StageVideoAvailabilityEvent.STAGE_VIDEO_AVAILABILITY, _onStageVideoAvailability);
That seems reliable. enableStageVideo is just a function to set up the stageVideo variable, and its viewPort.
