howto reduce streaming latency...

[arri]

i'm on a very simple setup;
a local network, with one machine running QTBroadcaster and Darwin Streaming Server.
3 other machines on the network will recieve the stream.
this works fine, but the latency between camera input and stream-output is over 10 seconds. Tipically about 12.

i tried several things, like setting the 'Buffer Delay' in QTBroadcaster to 0 or 1, but this didn't change anything.

does anyone know how to reduce this delay to an absolute minumum? (< 1 second?)
is this maybe something that can be configured in the Streaming servers' config?


thanks
