Sorry I can't help... but I happen to be in the exact same position. Have
you found a solution? I keep finding your same question all over the net!
This seems like it should be easy.
> I am trying to setup my Windows vista Media Player as an UPNP client. I have
> an Xbox 360 and three windows vista machines in my home. One of the machines
> is a media center with playon and rhapsody. My Xbox can see and play upnp
> media from all of the various upnp media sources in my home. Among these are
> PlayON, Rhapsody and the music collecitons from all of the windows vista
> machines via upnp. I would like to be able to play upnp media between the

> rhapsody on my other windows machines from within windows media player. I
> can see the upnp sources in network neighborhood however when i double-click
> the icons it seems not to open the media. The only media i see inside of the
> windows media is the other windows media music collections.
> This may seem weird but its important for me to be able to view the media
