I have had iStopmotion for a couple of months now and it has been working fine. I've used the built-in iSight with iStopmotion with no problems. Recently I've been using a video camera and connecting it via the firewire port. After using the video camera, the built-in iSight started acting up. It doesn't seem to be something wrong with the camera because it works normally in Photo booth. Is there anyway to remedy this problem?
This is what the problem looks like. notice how upset I am
