I just purchased an iSight to go with my 2x2 G5. When doing a oneway video conference with my PowerBook G4 (G5 --> Powerbook), my outgoing bandwidth usually approaches about 100k/sec outgoing (measured via MenuMeters), but inidicates a 15fps framerate. Why is it not rising above 1mbps outgoing, when I have it set to "No Limit" and both machines are on a 100mb network?
