You can also try ffmpeg://rtsp://unicast_ip:port/multicast/trackn

While I do not understand this sentence, please understand that all help
requests on this list require that you post complete, uncut output of MPlayer.
In your case, it probably does make sense to really cut, but you cut too much;-)

The two lines you posted are (completely) unrelated: The first is a warning from
the decoder (that you may disable), the second line is the status line that
shows the current time of the video stream (if you do not receive audio).
