Good webcasting software?

I want to broadcast a weekly dj set over the internet. I slapped a dual-boot on my recording pc, which is equipped with a M-Audio 1010.

I should mention that it's a dinosaur dell. I tried "U-Stream Producer," but it wouldn't run because of my shitty onboard video. I don't have a lot of cash right now. I also tried "Real Producer," but it wouldn't "hear" the 1010.

Google is no match for experience. Any help or suggestions would be highly appreciated. Thanks!

doesn't adobe have a flash one? I forget the name though...

Thanks, I'll check into it.
