How to read a DVD with VLC stream ?

[parfia]

I read very well an HTTP stream from my PC with :

cvlc my_freebox_stream --sout '#http{mux=ffmpeg{mux=flv},dst=:8080/}'

With in my userbouquet :

#SERVICE 4097:0:0:0:0:0:0:0:0:0:http%3a//192.168.163.10%3a8080: HTTP 8080
#DESCRIPTION HTTP 8080

But I do not success with :

dvdsimple:///dev/sr0

cvlc dvdsimple:///dev/sr0 --sout '#http{mux=ffmpeg{mux=flv},dst=:8080/}'

I have tried with UDP stream too, but I do not success to read it on VU+ uno.
cvlc my_freebox_stream --sout=#udp{dst=destination.ip:1234}


Thank you for any help.
