Hi, I am trying to have a video conference with a friend of mine using ichat av. I have a logitech quickcam, and i am using a program called ichatusbcam to allow ichat to work with this camera. When I click on the green camera icon next to my screenname, the preview comes up, and the camera is working fine, but when I try to video conference with my friend, there is errors. I'll invite him to a video conference, he'll accept, and then it will say I canceled the conference, and it will tell my friend he didn't respond to the request. Then an error pops up and it says "There was a communication error". Does anybody have any suggestions on how I can get the video conferencing to work? Any help would be appreciated.
