A good video "broadcasting" utility is the WMV VCM 9.
It allows you to broadcast audio and video over the internet. But you need a good CPU to encode video on the fly, and than broadcast it at the same time.
I have all cyberlinks software, and I'm not saying its its not good but I like my Premiere Pro from Adobe a whole lot better, but I don't stream realtime, I believe you can install a third-party plugin to achieve this. Check it out, it rocks.
