I have a new Powerbook and am having troubles using iChat video with one of my friends, although I can contact and use iChat video with another friend. The friend whom I cannot use iChat video with, is able to contact and use iChat video with the same friend I can contact. It sounds very confusing, and is frustrating. Both myself and the friend I cannot use iChat video with use Sympatico High Speed. He is using a new iMac connected to his sympatico router, I am using wifi through apple airport express.
