I've been having a difficult time with trying connect between two computers to video chat via iChat. I have done my research, updated ports, etc. using these links: http://docs.info.apple.com/article.html?artnum=301641 and http://docs.info.apple.com/article.html?artnum=9805. The error showing up reads "Insufficient Bandwidth.." and I have set my streaming speed off automatic like told in above links, have added iChat and iChat AV ports as well, but yet I am still getting errors. In the Connection Doctor it is telling me "Chat ended with error -22" which i've researched means: -22 unitEmptyErr Driver ref num specifies NIL handle in unit table which I am not familiar with. How do I resolve this issue? Also, what is the difference between the green camera that is layered and the one that is 2d? There are certain ones that have layers beneath the green camera icon and some that do not. Thanks in advance for any help!
