I just bought one of the 12" G4 PBs with the free iSight camera from Amazon. I can't get the iSight to work. According to the documentation that came with the iSight, third-party applications won't work without iChatAV installed -- and of course Apple doesn't include it with the iSight (amazing!). I've tried several of the third-party applications that are supposed to support the iSight, and none will recognize the camera. According to ASP, the camera is recognized by the system, and when I plug it in, iChat (the non-AV version) launches automatically and the green light on top of the camera turns on, and then after a few seconds, goes out. What gives?
