In order to play media you will need to find another device which supports
the AVTransport service. This has the play() and stop() actions.


Agreed, and I know the PS3 is a only a player, my question was why Google
Media Server, Tversity or cybergate media server are not detected as
AVTransport service ?

because the 2 previous services, will list was media is available, but
doesn't have to had them on there server, it can be on the server than
reside the AVTransport service.

do you have a sample of AVTransport service (prefenrencly in java)  and how
the mapping is done between the application that had the contentdirectory
and the connectionmanager services ?


for Jetty, I think the latest version can use NIO from grizzly (

)
