Sets the signal monitoring rate.

This will actually call SetupSignalMonitor() and TeardownSignalMonitor(bool) as needed, so it can be used directly, without worrying about the SignalMonitor instance.

See also:: TVRec::SetSignalMonitoringRate(int,int), EncoderLink::SetSignalMonitoringRate(int,bool)

Parameters:

rate	The update rate to use in milliseconds, use 0 to disable.
notifyFrontend	If true, SIGNAL messages will be sent to the frontend using this recorder.

Returns:: Previous update rate
