Sounds like there is an initial connection.
Sometimes more than one port is used, one to
handshake, another for the stream.  Could be
a firewall blocking it?  I'm not sure about QT.

Could you have a version mismatch?  Might the compression
algorithm not be installed on both sending and receiving
computers?  Sorenson still costs money.

In the early days a computer was used to capture/digitize
the stream, and then it was sent to a second computer
for compression (computers were not fast back then),
and that stream was sent to the server.  Could there
be an issue there?  The first few frames would make
it to the server, but then the single computer doing
capture and compression would bog down, and interrupt
the stream.  Possible, but only if you have a bad
hardware, or slow hardware, or the resolution of the
web cam, or digicam, is set to high.  

You do not mention what method the cam is connected to the
first computer.  USB 1?  USB 2?  Video card?  Firewire?
Composite?  RGB?

Have you tried sending a canned QT movie to the server
from the capture computer?  This bypasses capture and
compression and allows just the transmission to be
troubleshot.

Hope this helps.
