I have two different TV tuner sources. (1) OTA ATSC using a PCTV Stick and (2) OpenCable from a Comcast CableCard plugged into an HDHomeRun Prime. Each has a different program guide providerI'm trying to download the program guides for both sources automatically. Is this possible?I recognize that I could probably map the ATSC channels to the matching Comcast channels. But that doesn't pick up all of the OTA stations in our area.
