I have an AIM account and use it with iChat and my friend has a .mac account that she uses with iChat. When we tried to set up a video conversation, it sends the invite and one of us accepts it starts to set up the video conversation. Then it stops and on her comupter is says "could not start becasue (her name) did not respond" and mine says "could not start because (my name) did not respond" when the coversation was initiated on one end and accepted on the other.

Hi ees86,
You state here you are using a OS level that is below the point where Apple introduced you seeing the error log.
You are having what people on 10.4.7 and above are referring to as the Error 8 problem.
This is about ports not being open as the simplest cause.
Check the Mac Firewall (System Preferences > Sharing > Firewall tab.
If it is On then set the ports as the second pic here

Also check how you have those same ports opened in your modem.
If you are using Port Forwarding then it is likely the device is doing NAT as well.
There can be conflict with the way different devices do NAT.
If you have UPnP then switch to that.
It might be only one of you has to change

Test with test accounts as well.

If you have a modem and a separate router both should not be doing DHCP (Distributing IP adddreses to your LAN) as this causes SubNets that overlap.
Also iChat does not like it if two devices both do NAT based port openings. Use UPnP where you can.
