[GnomeMeeting-list] Connection Problem

[Scott Mackenzie <smackenz brad ac uk>]

Hi, I've just installed the latest redhat 7.3 kernel (2.4.18-4) and its
got my webcam working.  I've been playing with gnomemeeting (bundled
version with Redhat 7.3) for about an hour now, and I have a bit of a
problem.

(by the way, its a full install of 7.3, and all the gnomemeeting
programs are installed)

I'm testing this over a LAN from a linux box to a WinXP box with
netmeeting 3.01.  When the XP box didn't have a webcam attached I could
connect from gnomemeeting no problems, and on the XP box it would
display the view from the webcam connected to the linux system.  No
matter which way the connection was established -- linux to XP, or visa
versa it would work perfectly.

Next I connected a webcam to the XP box, and installed it correctly. 
Anyway the webcam worked on the XP box itself, but now when I connect
using gnomemeeting (either directions -- XP to windows and other the
way), it doesn't work correctly.

What happens is the call goes through fine however it only stays
connected for about half a second, and I get about the first image from
each webcam on each system, then the connection is cut.

Here is the output from gnomemeeting's History window:

I ran gnomemeeting in debug mode, and here are some main debug messages:

Anyway, thats about it.  Have you got any ideas as to the problem here? 
I would really appreciate some help.  There is no firewall blocking this
connection.

Thanks

Scott.
