void StoreAutoTune();
Saves the fine-tuning information for all channels. "Fine tune" each channel available in a given area using the AutoTune method and generate a table of channel information. When all of the channels have been "fine tuned", then call StoreAutoTune to store all of the channel information. For more detailed information, refer to the Microsoft documentation for IAMTVTuner.StoreAutoTune.
