DS216 fails to stream DSD music to my network player

[bubbleguuum]

"Illegal Mime-type" is a standard error for SetAVTransportURI (code 714 or 716 I do not remember), thus returned by the renderer and displayed by BubbleUPnP. Basically, it doesn't like the mime-type which can be due to either not supporting DSD (likely if it does no advertises it and 'mime-type check' was disabled in BubbleUPnP to force send the stream), or it supports it but BubbleUPnP (SetAVTransportURI) or the media server (http headers for the stream) does not set the exact mime-type the renderer expects. Mime-types are evil, although in that case I bet this renderer does not support DSD via UPnP.
