I've been trying to get iChat AV to work with my sister who lives across the other side of Australia. We've both looked at what you need to get it going and we've both got everything: iSight cameras, G4 machines, up-to-date OS versions, broadband DSL internet connections... It allows us to invite each other to do a video chat, but when it tries to connect us, the window freezes and then goes green and it says "Not enough bandwidth to obtain a connection" which is not true since we're both on broadband connections. We've tried altering the bandwidth limit in preferences and that didn't change a thing. Is there some way that perhaps one or both of our machines (mine's a PB 17") is not detecting that our connection is in fact as fast as it is? Have we got it set to think we're on a dialup or something? I don't know and Applecare aren't much help (it usually takes calling them 3 or 4 times to find someone who knows what a solution to my problems anyway). Any thoughts? Anyone had a similar problem? Thanks in advance. I'd love to do a video chat with my sister so I can see my two nieces. Chuck.
