All I do is right-click on their name and choose "Invite to One-Way Video Chat" and the camera light does come on up top. I never have problems on sites like Stickam or anything, but for some reason I have yet to be able to get anything going on iChat. The person I was trying to video chat with did say that when they accepted my request for video chat, that it prompted them to buy a camera. So, I'm thinking that it may be on their side, but I'm just not 100% sure and was hoping that someone on here has had experience with this.
