macromedia flash flashcom: Hi,

I've installed the FCS 1.5 into my server. I can run the sample script at the
localhost without a problem. But when i tried to use it on the web, i am
running into a failure to connect. Not sure where i go wrong. In my IIS, i
created a virtual directory for the videoplayer folder that contain the flv. so
in my actionscript, i put "rmtp:/mydomain.com/videoplayer/" but i hit the
connection problem. can someone tell me what's the right way to do it through
the web? thanks
