Error -8 Mac to MacBook

Hi,

I have a 733 MHz Powermac G4 w/ 1 MB L3 cache and 1.5 GB SDRAM. In the past I have successfully video conferenced with one friend who uses a G5 iMac and another with a 13" G4 Powerbook.

I recently bought my girlfriend a new 13" MacBook (OS 10.4.9) and I cannot seem to video chat with her (or any other MacBooks for that matter).

I am using a Netgear WGT624 Router and my girlfriend is using a Lynksys DCM425.

I have read most other posts on this subject so I have already:

Increased iChat's bandwidth setting on both computers
Updated Quicktime Streaming setting on both computers

Here are the Error Log details:
