Your player seems to be downloading two 8 MB MP4 files, which is why the load time is so long. It is unclear what the mp4 files are used for. The best thing to do would be to use the JW Player’s Wizard (http://www.longtailvideo.com/jw-player/wizard/) to pull the RTMP stream from your stream source, and compare that against the player you created. There should be no load time, aside from any buffers on the client side. The EMS does not buffer streams.
