I have a Netgear MR814 wired/wireless router running into a 1.5 Mb/s cable modem. When I try to video chat with someone I can see their video and audio clearly, but they see mine very jerky, pixelated, and usally without audio. When I plug my computer directly into the modem and try, it works fine. I have ports 5060 and 16384-16403 open on my router. I am running a dual 533 G4 with iSight. Please let me know if anyone has any ideas.
