Media Server :: Live Streaming H.264 Not Showing Video

I'm using FMLE 3.1 to stream live video encoded with H.264 format with FMS 3 and Flash player 10 + AS 3 to connect to the stream. When I connect to the stream, just the audio is played. I'm able�even to get the metadata information about the video, but I just receive the audio. I already tried some stuff like

1. "Flash 10 won't play live stream H.264 after iTunes install"�[URL]. I tested it in a complete different environment than mine, but the same result.

2. I've tried some format to play method, but this is just to play files
ns.play("mp4:saple.f4v"); ns.play("mp4:sample");

3. Also read "How do you watch and record a live h.264" [URL], but I don't get even to play the stream at first place. This is the code I'm using

import flash.media.Video;
var video:Video = new Video(720, 480);
var ncVideo = new NetConnection();
this.ncVideo.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
[Code] .....

Another detail is that when I record the video to a file for instance "sample.f4v", I put this video in the FMS but when I connect to this stream I receive the "FileStructureInvalid" error message. I went from changing the extension to .flv [URL] to the solution to flatten the files [URL] but this is not the case because I'm using FMS to stream the recorded video.
