You don't need Adobe Flash Media Encoder for re-broadcasting RTMP streaming. Just find RTMP URL and use it in a player like Flow Player or commercial JW FLV Player...
You can find some samples here:

If you have Linux, use rtmpsuck to find all the parameters of an RTMP stream.
If you use Windows, try freeware
