I'm not certain what is causing this problem, but the strangest thing happened. I have an iSight at home and at work and infrequently video chat with my wife. I also have recently added a Griffin Radio Shark to time shift radio programs and capture them to my iPod. Today when I tried to either vido chat or audio chat with my wife, all I could get for audio was the FM station that Radio Shark was last set to. She couldn't hear it, and could hear me, but I couldn't hear her at all. She confirmed that the Radio Shark was blue, not red, so it wasn't recording. Also, the Radio Shark application was not on. She confirmed, no little black triagle under the dock icon. I know that Radio Shark has a start up application that is used for background time shift recordings. I'm wondering if that was doing it. Has anyone else seen this behavior in a similar set up? TIA, Rob PS: Yes, I'm going to ask Griffin Tech Support as well.
