Anyone have experience with it?

It's the latest project I was working on last night. Wanted to get a livestream to my web server using LongTail (http://www.longtailvideo.com) but am having issues with getting the server to recognize. I am using default ports (5080, 1395, 80). Any suggestions on programs / apps I can use to test my RTMP stream? Or does anyone have a for dummies guide to get started? I'm sorta out of my element on this one
