making Mac iChat video work with an AIM account

After months of frustration, Yahoo technical and I figured out how to video conference using:

• Mac OS X 10.4.10 (Tiger)
• iChat (3.1.8)
• our AOL Instant Messenger (AIM) Account

For reasons we don't understand, the default AIM server setting doesn't work.

the fix that worked for us

1. Open iChat preferences and click on the Accounts tab
   
2. Select your AIM account
3. Click on Server settings
4. Change the default port (5190) to Port: 1080 (at the top - no need for a proxy server)
   
5. Restart iChat

[This also works for .Mac accounts - free or paid. Change the default port from 5060 to 1080.]

Yes, we have Apple's firewall on, and a Netgear router firewall in action.
