Subject: [flexcoders] Flex2 (beta2) app causes FMS2 to drop application

I have been playing around with two Flex applications.
One has been written by Brian
http://flash-communications.net/technotes/fms2/flex2FMS/index.html
<http://flash-communications.net/technotes/fms2/flex2FMS/index.html>  and
the other one is by Christophe Coenraets
http://coenraets.com/viewarticle.jsp?articleId=98
<http://coenraets.com/viewarticle.jsp?articleId=98>

Brian's example works fine for me but Christophe's example gave me problems.
I have sort of merged the two apps and have narrowed the problem down to one
line of code:

nsPublish = new NetStream(nc);

When I run this line I see the following in the FMS2 console:

Dropping application (flexvideo/_definst_) message. Clients not allowed to
broadcast message.

I can't figure out why this occurs, especially since Brian's app is very
similar. Here's my complete MXML code. All you need on the FMS side is an
app 'flexvideo' - no server side code is needed.

Note: some of the vars decalred here aren't actualy used. Can you shed any
light on this problem?
