Finally an intelligent response! Thanks Chuck. I followed the procedure
recommended by MVP Jonathan Kay on his web site in which he says that the
built-in firewall of XP opens the necessary ports for Messenger to pass the
video/sound signals whereas other firewalls such as ZoneAlarm will block
those ports. I uninstalled ZoneAlarm and enabled the XP firewall and all
those ports - 5004 to 65535 - were still in stealth mode and I still
couldn't get video and sound. I was even brave enough to disable the
firewall completely and still no video/sound in the M.S. messengers although
there is no problem in the wizard.
The implication of all this is that they - the MVPs - have no idea why this
thing will not work beyond the firewall issue. Some of my friends have no
video/sound problems with the M.S. messengers using the Windows firewall and
everybody can use Yahoo's messenger.
You mentioned valid reasons pointing out that the Windows messengers are
superior to the Yahoo Messenger because they use more direct paths between
conversant machines. Could it be that even though I enabled the XP firewall
the UNP&P was still not enabled and Messenger needs it for video and sound?
Thanks for your help,
Peter
Peter,
UPnP is the key to it. And the problem, too, cause not all firewalls
/ NAT routers are UPnP capable. Not only do YOU need a UPnP capable
router, but your friend on the other end needs one, if you want to
converse with him.
And you both need Windows Messenger, not MSN Messenger, if you want to
use both video and sound.
Miss just one of these details between the two of you, and you're
another case posting here "I can hear my bud but he can't hear me..."
/ "Can't connect..." / "No picture..."... I had a Windows Messenger
a/v conversation working once. The sound was definitely nice. The
picture was tiny (M$ has been promising to improve that), but clearer
and smoother than Yahoo Messenger.
But that was just once. 90% of the time, Yahoo Messenger is the only
solution.
M$ is so smug about all of it too. Technically superior audio /
video. Windows Messenger (developed by one M$ division) has audio /
video but lacks file transfer ability. MSN Messenger (developed by a
different M$ division) works on Windows 2000, but won't do audio (or
is it video, I forget).
One day, Yahoo will solve the bandwidth / latency problem. Then M$
will lose that edge too. Like Sony and Betamax lost to VHS Premium
Quality.
Cheers,
Chuck
