Here is the setup: Me: Mac with iSight and iChat and Linksys BEFSR41 router Parents: Windows XP using AIM 5.9xxx and Logitech Webcam, no router We have been able to Video chat without any problems as recently as 3 days ago. Beginning last night when we try to connect we keep getting a "User (My Name) did not respond" error even though we get the invitation without problem and I click on "Accept". This had never happenned before and no new software was installed on either end. The error message on her end indicated that it was a possible firewall issue on my end. So I first tried the opening the ports Apple suggests to no avail. Then I tried taking my router out of the loop and connecting my Mac directly to he cable modem. It again did not connect, but now I would get a message immediately after I hit "Accept" that they had terminated their video and they got a message that I was not accepting video. Any thoughts, other than getting my parents a Mac, LOL. If there is ANY other solution out there for video conferencing from a Mac to a PC, I am open to any change. I would even pay if it wasn't rediculous.
