I have both the above installed and would like to know in your opinion the best to use. Currently as I have limited experience in trying each out with my web cam, MSN seems better with video than Yahoo, which seems to jerks more. Question 1)Is it possible to have one user using Yahoo and another MSN calling each other? 2) How critical is the refresh rate of the camera, I have a logitech quick cam(no idea the refresh rate)? 3) Are there3 better software out there(FREE)?
