Serviio

I'm trying to use Serviio on a QNAP 251+ NAS to stream to a Marantz 7701 DLNA pre-pro, using Media Browser on a Windows PC for the control point. The pre-pro was found in the Status window and is active, yet playback of files always goes to the PC. I tried making every device inactive but the pre-pro and playback still came to the PC only. Is Serviio capable of a 3-tier architecture?

MediaBrowser is not a controller, it's just a renderer. You'd have to use a diferent application, like BubbleUPnP as the control point.
