This function maps the TV channel to a frequency and searches for the most precise frequency for this channel, in the area. Calling this function for every channel in a region or country allows you to create a table of channel and frequency information. Once all channels in the region or country have been scanned, use IltmfTVTuner::StoreAutoTune to save the channel information.
For more detailed information, refer to the Microsoft documentation for IAMTVTuner::AutoTune.
