Vista - Cannot use video messaging with someone running XP

My webcam is working fine. When I try to do video conferencing with about computer running vista everything works fine. But when the person I am calling is running XP my webcam does not appear to work. The person I call cannot see the webcam and the webcam does not even appear on my screen. Is there some problem with a vista machine and an XP machine trying to video conference through live messenger. This is driving me crazy! Please help.

Hi Mastroj,

Video conferacing has nothing todo with the OS your using, it depends on their configuration and firewall settings

If they cant see you during a conference then the problem is on their end, if you cant see them then its a problem with their webcam or its on your end
