Help with live streaming apps.

Hey y'all. I'm trying to find an app that's relatively easy to use and will allow me to stream audio and video over the Internet and share links to the stream via Facebook, twitter, etc. I realize this has been brought up before, but I couldn't find any answer so I thought I would revive the topic. Hope that's okay. I've tried Livestream and Ustream but I couldn't get them to work properly. Any help you can give is sincerely appreciated. Thanks! :-)
