this is a little bit off-topic, but maybe you can help me. I'm just trying to write a little application to interact with my media controller / renderer (Teac WAP 4500). I notice, that the Teac sends a header: "getcontentFeatures.dlna.org=1" - but what does this mean? Can I use it to trigger some specific actions if a button on the controller is pressed? Is there anywhere a documentation? I just noticed, that the Ps3 Media Server uses this request parameter if present.
Any help is appreciated.
