Extract rtmp url and video with rtmpdump

[gallina94]

Hi all,
i'm trying to extract video from this url
http://www.web-tv.135.it/
the channel is italia2. I'm able to get all the parameters to pass to RTMPDUMP using rtmpsuck. The final command is the following

rtmpdump -r "rtmp://edge3.786cast.tv/live/italia22" -a "live/italia22" -f "MAC 11,1,102,55" -W "http://www.786cast.tv/jplayr.swf" -p "http://www.786cast.tv?u=italia2&vw=500&vh=500" -y "13338442377083" -o prova.flv

but i get this error

RTMPDump v2.3

Anyone can help me?

Thanks
