How do I correctly run this rtmp stream I got with Wireshark

[fastidious]

Hello everyone!

I would really appreciate your help...
I'm trying to use Wireshark to get the rtmp link to a stream I'm watching on this webpage:
http://isramedia.tk/2/%D7%A2%D7%A8%D...8-%D7%97%D7%99
(this stream is live 24 hours a day)

I got this info from Wireshark:
rtmp://live.yycast.com:1935/live/_definst_
nexter_5234

So I tried to run it with MPlayer on Ubuntu linux (12.04 "precise") with:

rtmpdump -v -r rtmp://live.yycast.com:1935/live/_definst_ -a live/_definst_ -W http://cdn.yycast.com/player/player.swf -p "http://isramedia.tk/2/%D7%A2%D7%A8%D7%95%D7%A6%D7%99%D7%9D-%D7%9E%D7%99%D7%A9%D7%A8%D7%90%D7%9C/%D7%A2%D7%A8%D7%95%D7%A5-2-%D7%A9%D7%99%D7%93%D7%95%D7%A8-%D7%97%D7%99" -y nexter_5234 | mplayer -

Adding quotation marks doesn't work either:

rtmpdump -v -r "rtmp://live.yycast.com:1935/live/_definst_" -a "live/_definst_" -W "http://cdn.yycast.com/player/player.swf" -p "http://isramedia.tk/2/%D7%A2%D7%A8%D7%95%D7%A6%D7%99%D7%9D-%D7%9E%D7%99%D7%A9%D7%A8%D7%90%D7%9C/%D7%A2%D7%A8%D7%95%D7%A5-2-%D7%A9%D7%99%D7%93%D7%95%D7%A8-%D7%97%D7%99" -y "nexter_5234" | mplayer -

I get this error msg:

Could anyone help me fix the command I'm using, please?
Thanx in advance

Thank you very-very much !!!

But, could you please tell me how to run it using mplayer?
like:

rtmpdump -r "rtmp://..." ... | mplayer -

(I need some of mplayer's functionalities).
Is the parameter that you used after "jtv=" in ffplay the same as the parameter -y in rtmpdump?
