I don't understand everything of what you say, but I'll try to answer
anyway.

Yes, the network stream sent by vls is UDP/IP. In the network packets,
vls puts MPEG TS packets. Vls doesn't put MPEG PS packets inside the
network packets because they don't have a fixed size, whereas MPEG TS
packets do. The fixed size of MPEG TS packets is very convenient for
network streaming.
