In my DMA, it looks like OTA stations will not be delaying their analog shutdown except for the PBS channels. They say that Feb 17 is still the date for them. My NBC station will be switching from channel 36 to 12 and my ABC station from 33 to 36. I do not have HD LIL and rely on the OTA tuner in my HR20-700. I wonder if these channel changes will affect the OTA program guide information?
