Manycam and integrated webcams?

I am trying to use the manycam program with my Dell laptop with built in webcam. The program works just fine as long as I am not streaming live. I would like to use the program while streaming live on certain websites, but I can't seem to figure out how to change the settings on my webcam itself so that said websites will recognize my cam. I can stream without the program, but would like to use the program so people can't steal my video and reproduce else where. Any ideas what I'm not doing right?? I know it works, I've seen someone else do what I am asking, just can't get answers from them. THANKS!!
