unfortunately dvbstream does not accept more than one "-i 127.0.0.1 -r 5001" 
option. So I tried "-i 224.0.0.1 -r 5001" but mplayer does not play so good
(it loses many frames and the playback is often corrupted)
and mencoder refuses to use the same "rtp://224.0.0.1:5001" of mplayer. They
don't use the same play address at the same time. It is very strange.

Maybe this is caused by the fact that I run on a slow 700Mhz cpu all the 
programs at the same time, do you agree?

Thanks anyway.
