Fake webcam programs such as ManyCam have been banned from Chatroulette on the new version. Unless you enable a real webcam, you cannot connect. There is a work around for this ... want to know what it is?
Chatshock was hesitant to release this information at first. We don't want to counter-act the efforts of chatroulette to improve the service. However, The bottom line is that it's only a matter of time before it becomes common knowledge anyway.
