I understood that the first time, But besides that statement of truth, I don't 
understand what you expect VLC to do about it?

VLC has interpreted `udp://10.0.0.2:1234` as a command to listen to unicast 
UDP traffic to the default port and any local IP, from remote IP 10.0.0.2 and 
port 1324. We can't change that, lest we break existing playlists and command 
line scripts.

No, we obviously cannot redefine the VLC MRL syntax in backwards-incompatible 
fashion 25 years after the fact.
