In this scenario we have two Windows XP computers, both running MSN
Messenger 6.1 with no software or hardware firewall at either end.
Public IP to Public IP.
Both of us run through the Audio/Video Tuning wizard and the Mini DV
camera shows up fine. From the Actions menu, one of us chooses 'Start
Video Conference', and I transmit audio/video just fine to the other
end, but I only see a black screen and no audio.
We have both re-run the tuning wizard a bunch of times and try to
reverse the invitation initiation with same results.
What's interesting is that if we both run _Windows_ Messenger with all
other environmental variables remaining unchanged, everything works
like a charm.
Also, if I run MSN Messenger 6.1 and he runs Windows Messenger 4.7, it
works like a charm, except we can never stay connected for more than 2
minutes without it rudely aborting the video conference.
The reason I need to run MSN Messenger is because it has the video
re-size options that Windows Messenger does not (or I cannot find it).
We're planning a video conference that will be projected and the
Windows Messenger video window is too small.
Any ideas here would be helpful. :)
