I was able to capture this stream with
Replay Media Catcher 4 in the RTMP recording mode. It showed the following URL
Code:
rtmp://cp39920.live.edgefcs.net:1935/live<break>ustream-sj@23780
You can also download RTMP streams with freeware
CooJah + Blader,
Orbit Downloader,
StreamTransport,...
And you can try to capture RTMP streams in real time while you listen to them using freeware
CooJah (without Blader), Orbit Grab Pro.
If you use Linux, try rtmpsrv or rtmpsuck.
