I'm on Skype with my family over seas for the very first time. We are connected now except no video. Why? we both can see ourselves on screen under video setting preference. But not on Skype screen. Please help. my system is os 10.5.8, Skype 2.8. my family is using windows 8 they just bought last week. Not sure what Skype version they got. Audio is clear and perfect.
