Hey, I'm new to these forums and was wondering if anyone could help me with a problem I have been having with my iChat. I have a 24 inch. iMac that I received about two - three weeks ago. Whenever I try to video chat with someone they appear on my screen all pixelated, and there is a delay of motion and sound. With some people it is worse than others. I have another mac in the house (for different use) and the picture when i chat with that one comes up wuite clear. Any suggestions? All help is greatly appreciated!
