Mike,
To connect to Wowza you need a Flash player and use rtmp url.
It’s a good idea at this point to get the Wowza example players so you can test easily. Download and install Wowza Pro 10 (you do not have to run Wowza, this is just to get the examples), then open this page:
[wowza-install-dir]/examples/SimpleVideoStreaming/client/simplevideostreaming.html
This html page load the swf in the same folder, which is what really connects to Wowza.
In the Stream box put rtmp url:
rtmp://174.129.214.73/simplevideostreaming
In the Stream box put:
merry_melodies_falling_hare.flv
You can use http to check the server, put this in a browser.
