This is a GREAT app!!! Very MAC friendly. I have been using this app since version 4 and have never had any problems or difficulties with it. It works with my sony vidcam and my firewire cam on either my G4, G4 powerbook and DV iMac running either 9.2.1 or 10.1! It was the first and as far as I know the only video chat program to work with OSX.
