I have a Power Mac G4 MDD with Mac OS 10.5.8 which is the max. for this machine... And currently have a Skype version 18.104.22.1686. Installed. I have a family over seas just got windows 8 and want to communicate via Skype. The audio was super clean and we could talk live, but no visual. I could see how my isight was working since I could go to the video tab and see myself ( not in the Skype video chat window) in the video setting window. My family said they could also see themselves just for a sec. on their screen, but goes away immediately after being logged on to the Skype. Could you tell me what's happening and how to resolve the issue so that we could video chat?
