The IScanningTunerEx interface is an extended version of IScanningTuner and is exposed by the BDA Network Provider filter. It inherits from IScanningTuner and permits direct control of a tuner that supports searching for valid programming. The client must provide a valid tuning space (using ITuner::put_TuningSpace or ITuner::put_TuneRequest) before calling any of the methods in this interface. This interface is meant to be used in conjunction with the IBroadcastEvent outbound interface.
