The weird thing is I can use the Media Player as a UPnP control point (client) to browse through media on UPnP servers, but unable to use it as a UPnP renderer.

I'm using foo_upnp in foobar2000. It has no problem seeing other UPnP renderers...

Is the UPnP renderer not activated by starting the Media Player, or is it a compatibility issue with foo_upnp? Anyone with experience in using the Media Player as a UPnP renderer?
