So, the short answer is that this combination doesn’t work. Apart from the fact that the pymeds pymediaserver expects to only do video, the MP101 seems to be talking a different uPnP dialect. I’ve done some hacking to get it to the point where I crash the MP101, but I need to play more. I’ll be away for the next week in Kirkland so I guess I’ll hack more when I get back home near the hardware.
