Hey. I have a white 2.0 ghz white macbook. When I try to start a multiparty video conf with the apple test bots "appleu3test01" "appleu3test02" "appleu3test03" it fails...however I distinctly remember being able to do this with my friends. I was wondering whether you guys are finding similar problems. The error I get says "Cannot start video chat. Your computer is not capable of initiating a multiperson video chat"....any ideas?
