TV-Porinternet stream

I am able to sniff the stream in MediaBox and record in Blader. I would like to instead be able to record thru rtmpdump (2.2)

MediaBox gives me these settings

rtmp://206.190.139.28/live/sports10?id=1990
app: live
extra: AAAAAAIAAAACAAAAT0sAAA==
flashVer: WIN 11,9,900,170
pageUrl: http://www.janjua.tv/embedplayer/sports10/1/585/385
swfUrl: http://www.janjua.tv/resources/scripts/eplayer.swf
tcUrl: rtmp://206.190.139.28/live
playPath: sports10?id=1990

My understand is this should work in rtmpdump

rtmpdump -r "rtmp://206.190.139.28/live/sports10?id=1990" -a "live" -f "WIN 11,9,900,170" -p "http://www.janjua.tv/embedplayer/sports10/1/585/385" -s "http://www.janjua.tv/resources/scripts/eplayer.swf" -t "rtmp://206.190.139.28/live" -y "sports10?id=1990" --o "fox.flv" -v

but the server is rejecting it. Again, blader seems to be handling it find and I can not find any token in the SWF. I do not know if the extra field should be included or how it should be included.
