No video or talk

I had basically the same problems that you had once. I
ended up going to the Knowledge base and researching the
problem. There is a situation where the Router needs
certain ports opened to enable the signal to get around
the firewall. I and a brother spent about 72 hrs out of a
48 hr weekend trying to make it right. And in the end I
got voice with him but no video. I have since learned
that his version of Win Mess might of had something to do
with it, and my sound card, an SB Audigy, might have been
installed improperly. Sorry I couldn't have been more help.
