Black DV video on MSN Messenger 6.1 but Tuning Wizard OK

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. :)

I have exactly the same situation. A short time ago, I cleaned up my system
and removed a run-time Dragon Naturally Speaking application. For a couple
of days, MSN Messenger 6.1 worked perfectly both
directions with my brother. Then, after installing another small program, we
were back to black screen no audio on my end. Uninstalling the other program
did no good! Evidently some 'dll' stayed in. My wife's system worked
perfectly with MSN Mess 6.1 until a few days ago, and now it is the same as
mine, black video no audio. We have no idea why. Evidently the problem is
caused by some errant 'dlls'.
Needless to say, both systems have had all the "hopeful corrections"
applied. They both connect through the same upnp router and cable modem via
the same model of onboard 10/100 lan.

Good luck,
Bob

Well I did end up solving the problem. Found another newsgroup where
someone hinted at the possibility of a faulty 802.1p implementation on
Intel NIC cards. Sure enough one of us had an Intel NIC card,
disabled 802.1p and msn video has worked better since then. We also
disabled the QoS scheduler - he had played around with QoS and now we
don't get disconnected either (which we were before we disabled the
QoS scheduler).

Lucky you! 802.1 and QoS have always been disabled on mine, and the latest
updates from Intel are installed. I even disabled the onboard NIC and
installed a another Linksys unit. With all this, if my brother in the UK is
on MSN Mess 6.1 and I use Win Mess, video and audio work fine!
