renatosaraiva.com.br: I need help to download a stream

[AGuy]

Here is the site: http://renatosaraiva.com.br/videos/demonstracao/1574

Looking in the source code I found this: var s1 = new SWFObject("/imagens/playerStreaming.swf","single","400","300","7");
s1.addVariable("streamer", "rtmp://187.45.247.20/vod/");
s1.addVariable("file", "LocalUser/renatosaraiva/413beca21b33932b8e9f00a488132fe6&cpf=32145697890") ;

I think "rtmp://187.45.247.20/vod/" are the host, and: LocalUser/renatosaraiva/413beca21b33932b8e9f00a488132fe6&cpf=32145697890 are the file, right ?

I try some comands: "rtmpdump.exe" -W "http://renatosaraiva.com.br/imagens/playerStreaming.swf" -r "rtmp://187.45.247.20/vod/LocalUser/renatosaraiva/413be
ca21b33932b8e9f00a488132fe6&cpf=32145697890" -p "http://renatosaraiva.com.br/videos/demonstracao/1574"

rtmpdump.exe -r rtmp://187.45.247.20/vod/LocalUser/renatosaraiva/413beca21b33932b8e9f00a488132fe6&cpf=32145697890

And I get the same erro Closing connection: NetStream.Play.StreamNotFound.

Using Wireshark I see some thing like "handing shanking" on packages, it means the site use some kind of encriptation ?
Any clue ?
