I have a system built around a KT400 mb with a 2500xp processor. I have tried a video link using netmeeting and hotmail with a modem link which reports a speed of about 44k bps. The sound is an on board system. The video is a bit jerky but acceptable while the sound is very poor and has an annoying echo. Is this all I can expect from a modem link. Is the result dependant on the software. I only have a cheap USB Zoomcam, would a better camera help. Would a separate sound card help. Would a direct PC-PC link be better, and if so how do you set this up.
I don`t think buying a new web camera will help. The better option to improve video quality is broadband.
As regards the echo, this is a common problem, and I found that Yahoo messenger is much better in this respect. The only way to fully eliminate it is for both parties to use headsets. The sound quality "might" be improved with a separate sound card, but I am doubtful. The quality of the audio connection does seem to vary from time to time, but try Yahoo Messenger first to see if it is better. You would both need a Yahoo ID, but this is free.
