Hi Lars,

I'm pretty sure that you need a streaming server.
QT Broadcaster, as far as I understand it, only records/provides the 
unicast/multicast, but not an (RTSP) stream, which is what QC needs.
This is where the QT/Darwin Streaming server comes in.

Another option would be using the excellent Wirecast app 
(http://www.telestream.net/wire-cast/overview.htm), which contains an 
integrated streaming server.
Using this setup, I had no problems displaying streaming video (coming from a 
URL beginning with rtsp://) inside Quartz Composer*.
Unfortunately its a tad expensive.

Oli

* tested in SNL/QC4, though
