dvbstream -f ... -udp -net ... with mplayer udp://... does not work

Hi, I just tried watching stream through dvbstream(cvs) -udp and mplayer(1.0_rc1),
but it does not work for me:

according to my .mplayer/channels.conf (which is OK for mplayer dvb://) line
CT1:506000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_2_3:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE:257:273:1

I tried to run
$ dvbstream -f 506000000 -udp -net 127.0.0.1:5001 1
in one terminal and
$ mplayer -nocache -noidx udp://127.0.0.1:5001
in another one, but I got no a/v from mplayer.
I got this output:


$ dvbstream -f 506000000 -udp -net 127.0.0.1:5001 1
