whats Ichat AV and where can I get it? my ichat wont work with aim for video. I tried amsn but I can only receive video, they can't see me, but I do see myself. I tried mercury, none of them seem to be as good as AIM to AIM or msn to msn on windows. I see Ichat AV on the internet and it looks pretty cool. I thought it was only for leopard but I see its for tiger. I downloaded an update version of it somewhere and it wouldn't install. It was the universal version, not the ppc. I'm on a mac book pro.
