Hello my laptop is wired to my Xbox 360 in order to provide wireless internet without the wireless Xbox 360 adapter using the windows feature "Internet Connection Sharing".
PMS detects an Xbox 360 in the status tab. The laptop detects PMS as a Media Device in the Network window for Windows.
However the Xbox 360 will only detect PMS running on the laptop providing the shared internet connection and not the original PMS connected to the router.
My setup looks like this in other words,
PMS (wired)-> router (wireless)-> laptop (wired)-> Xbox 360
