[vlc] Cant read an UDP stream

[Alexis Guerin]

Hi,
A few precisions about my problem:

I don't even get a blank window when I try to read the stream (just nothing 
happens).

I also can see some icmp packets (~ port 1234 unreachable)

It doesn't work either with a multicast stream.

It works well when I stream the file by runnibg vls and vlc on the same 
machine (start presentation localhost local1 --loop).

Please tell me what I am missing.
It is certainly obvious but I cant find it....

Thanks in advance for your help

Alexis
