Hey all, I just logged into iChat and noticed the green icon is only a telephone symbol, not the usual video. So I go into Preferences > Audio/Video and the video preview is now a white box with the text, 'This computer does not support video chat'. It's a brand new MacBook Pro, iChat has been working fine up to this point. I re-started and still the same message. Anybody know what might be wrong? And, how I can fix it?
