IChat AV 3.1.9 an 10.4.9 - clear video, no audio either way

Question

okay, I've read the threads and I've done the tips, but still this odd issue is happening:
With the 10.4.9 upgrade (this worked on 10.4.8) my iChat AV will connect clearly with video (iSight on a G5 iMac to a Core Duo iMac) but neigth person can hear one another. We can do an audio chat just fine and sound is clear. The Network appears to only be using 10-20 Kbps and I have DSL, the connecting computer is Cable. We are using Linksys WRT54g routers (wired over 100 Mb Eithernet) and have the ports open (like I said, this worked in 10.4.8).
I know it is something with me because the othr computer can connect to a MacBook Pro and has audio and video at the same time. I have tried:
- Uninstall Flip For Mac
- Check my NAT ports
- Check Quicktime bandwidth is 1.5 and iChat bandwidth limit is None
- iChat is 3.1.8
This is a real bummer. Your help is appreciated!

Hi Aaron,
Welcome to the Apple Discussions
IS your Linksys doing DHCP with Port Forwarding ?
If so sometime when you do an Update the modem or router will consider the New OS to be a new computer and issue it with a different IP.
Is the computer getting the IP the Port Forward settings are pointing to ?
Does this Linksys have UPnP in the Administration tab ?
Is it On ?
You should not be using two methods.
As UPnP allows multiple computers (different IPs) to use the same ports it provides a way around the the problem of DHCP issued IPs changing.
