I really like the ability to send audio files straight to the TV from Windows via Window's context menu's Play To function, or any other UPnP controller software. The TV seamlessly enters into SmartShare mode and plays the file, then seamlessly exits SmartShare when the UPnP controller is closed. My only gripe, and it's a significant one, is the lack of a screensaver when the TV is playing audio only in the SmartShare app. I realise there is an option to turn off the screen, but you have to dig through the settings to do this.
Is there a setting somewhere for this feature, or did they neglect to create it? If so, it seems like a huge oversight not having a screensaver in SmartShare mode when the DNLA/UPnP renderer is playing audio only.
