Wild media server (UPnP, DLNA, HTTP)

Need to know if there is a way to automatically check the availability of channels. The only way I can find is to select all channels, then right click and check availability. This takes a long time, and is inconvenient since I have to be in front of the pc to perform. If I don't do this, when I first start the server all the channels display (?) and choosing an unavailable channel from my tv causes it to lock up if the channel is unavailable.
This is currently the only feature keeping me from turning this software from a trial into a purchase.
