VOD streaming stop at client after 10 or 15 seconds - HTTP + RMTP in html object using SampleMediaPlayback.swf embeded - AMS 5

I created a HTML file to call object SampleMediaPlayback.swf passing the rmtp path of a mp4 file with 10:38 minutes of HD video.

Occurs that when I try it at the server all works fine but when I call it from the network in another client machine the html page is loaded, the video starts but after 10 or 15s it stops ...

At the AMS console I can see the streaming be created and the file been served as recorded.

At the log I can see PLAY and STOP with x-status 31 ...

Somebody knows how to solve this ?

Regards.
