How to detect on Windows if MinimServer (+BubbleUPnP Server) is actively streaming?

It is hard for me to say what is happening without seeing the trace log information that I requested in my previous post. My guess from what you have posted so far is that BubbleUPnP's urlcache.dat file might be a cache of streamed audio data. MinimServer does not use such a cache but streams data from the audio file "on demand" as requested by the renderer.
