All of these devices I listed connect to UPnP media servers and the media servers see them. However, I played around with Cidero and while it did see these devices on the network (per the log), it did not add them as renderers. I may have missed something that I needed to do in Cidero as I'm not familiar with the software but when they didn't show up there as renderers, I took that to mean they are UPnP but not UPnP AV compliant...ie, not controllable via UPnP.

Has anyone had success CONTROLLING any of these devices ?
