2) - I have Vista Home Premium with Media Centre. I have
my Denon Amp connected to my Network, and I can play music
via the denon remote. I cannot get Nevo Studio to see
the Media Centre as the server, and I cannot get NevoStudio
to see the Denon Amp as a output device.
I think the NevoSL works only with devices that are compatible with some protocol called "UPnP".
Unfortunately, I don't think either one of your devices (the Media Centre and Denon Amp) are compatible with this format.
