The address set  une the source code is the  standard address the should
always  be used  for SAP  announces. Since  it theorically  shouldn't be
changed, we didn't  care giving the option ti change  it easily yet. The
fact  it is  a  standard  address explains  why  your  system knows  the
assocaited name.  It is the same  for 224.0.0.1 (ALL-SYSTEMS.MCAST.NET),
224.0.0.5 (OSPF-ALL.MCAST.NET), etc...

Well,  that's not  exactly  things are  supposed to  work.  Once SAP  is
enabled as an  extra interface (as you did later),  Annouced streams are
supposed to  appear automatically in  the palylist. Channel  servers are
not used for SAP, and are now more or less deprecated.

The address and  port the VLC is listening for  announces can be changed
in the SAP interface options. However,  as I said before, it shoudn't be
unless you've got reasons to do it since these values are defined in the
SAP standard.
