DRM video playback - HELP PLEASE

Question

I have searched and searched and searched online but cant find anything and from what I can Adobe doesnt have any examples, but I am building an AIR desktop video player application and want to be able to play videos with DRM such as bought iTunes movies or dvd/bluray Digital Copy's(if possible, if its not go ahead and tell me please). What I had done so far was something like this.
var netconnection:NetConnection = new NetConnection();
netconnection.connect(null);
var netstream:NetStream = new NetStream(netconnection);
netstream.client = this;//This works
var netoptions:NetStreamPlayOptions = new NetStreamPlayOptions();
netoptions.streamSource = "videoFile.m4v";
netoptions.preloadEmbeddedData(netoptions);
function onMetaData(e:Object):void {
     trace(e);
function onDRMContentData(e:Object):void {
     trace(e);
Now, with a regular video file, the onMetaData event fires and traces out and works just fine. If I try and play an iTunes bought movie, neither the onMetaData or onDRMContentData events fire and I have no way of knowing what is going on. Any ideas? Any help or examples or telling me what Im doing wrong would be awesome. Thank you.

Well I dont know a whole lot about how DRM works, but from what i understand you download the permission to play the video online using the DRMManager class after you have received the embedded data by calling that preloadEmbeddedData that gives you the info that the DRMManager needs to be able to send the request to be able to play that file. But here is the answer to your question about the meta data
