UPnP must also be enabled on your Windows XP or ME computer. To do this, open the Control Panel from
the
Start Menu and select Add/Remove Programs. Select Add/Remove Windows Components and open
the Networking Services section. Click Details and then select UPnP as the service to add.
Network - RTP (Multicast)/MPEG-4
These settings are the IP address, port number, and Time-To-Live value to use for the video
stream(s) in multicast MPEG-4 format. Only certain IP addresses and port numbers should
be used for multicast streams. For more information, please see the online help.
