UPnP says it sits on top of TCP but only for the discovery and other stuff (like the former channel D in the old telecommunication times), but when it is about sending the content, it seems to be based on UDP using unicast protocol.

Simon : can you confirm ?

The audio data is transmitted using TCP and there is no doubt that in all cases the renderer has received an identical copy of the bits sent by the server. The discovery protocol uses a mixture of UDP and TCP.
