sometimes on DSL connections this component doesn't start to
download until it has completed the progressive downloading of all
the file .flv.
so the behaviour is that you can't see the progress bar while
downloading the file.
after the component has complete the download you see all the
progress bar full and then start to play the video.
the component stay freezed on the state "loading" and doesn't
pass on the state "ready" until the flv file is completed
