I could really use some help with streams kept on pegcentral.com. Their media server looks like it is Wowza Media Server and RTMPT protocol over port 80

The material is mostly content from local public access stations such as city government, school districts, etc Not very interesting stuff but there are some clips I really need to grab for a school project.

for example, here is the main launch page to a hosted video.

_http://swoccstudios.pegcentral.com/player.php?video=1cb8dffbf0da798cc9a2eed64a7daec8

After launching it in my browser I am able to gather the following info about this stream from capture file with Wireshark.

app
'peg_c_stream/?doConnect=12345&doPublish=54321'

flashver
'WIN 10,3,181,26'

swfUrl
'http://swoccstudios.pegcentral.com/flash/media_player_102908.swf?server=swoccstudios.pegcen tral.com&account=swoccstudios&pointer=1cb8dffbf0da 798cc9a2eed64a7daec8'

tcUrl
'rtmpt://beta-rtmp.pegcentral.com:80/peg_c_stream/?doConnect=12345&doPublish=54321'

pageUrl
'http://swoccstudios.pegcentral.com/player.php?video=1cb8dffbf0da798cc9a2eed64a7daec8'

play
'mp4:swoccstudios/SE_OlympicEvent_NOVI.mp4'

I've tried various commands but always end up quitting with
"ERROR: RTMP_ReadPacket, failed to read RTMP packet header"
if I use rtmpdump -r "rtmp://beta-rtmp.pegcentral..."

or

"ERROR: RTMP_Connect1, handshake failed."
if I use rtmpdump -r "rtmpt://beta-rtmp.pegcentral..."

It doesn't matter if I specify the port and which arguements I pass beyond that. May somebody please clue me in as to how I can grab their content with rtmpdump? Thanks in advance
