Sorry, that's wrong. UPnP on the router is to allow any device that supports it to do basic queries about current outbound connectivity and port forwarding. That's covered by the UPnP Internet Gateway Device specification. This has absolutely _nothing_ to do with the UPnP AV specifications. You do not need a router's UPnP support to use UPnP enabled media devices in your network. UPnP is a standardization group covering a vast amount of topics, not only media sharing.
