Windows Streaming Web Cam

I 've been trying to establish a web cam that is pointed out our back window. I call it the Alley Cam. Anyway, I was checking out The Head Nut web site The Head Nut and they have a streaming Windows 9 Media broadcast. I tried to do the same here using port 8080 but cannot get it to work. I think that RCN (Our internet provider) is blocking port 80 and 8080. I know they block port 25 for outgoing e mail (Thanks to Spammer Bastards) So i'm at my wits end. Any one out there know how to solve this? Please respond. Thanks.
