Fix a logic bug that would cause NTSC channels to have a NULL freqid if
fccchannelnumber exists. This is set for NTSC if the cable provider
uses a different channel number than the broadcast channel (common for
local independent stations) and possibly other OTA stations. Instead,
assume ATSC freqid only when "minor" exists.
On a tangentially-related topic, can someone review for me what I need
to do with respect to ATSC minor channel numbers and freqid?
Currently, I have the following freqid's for my ATSC channels:

Obviously some of these freqid's are wrong (e.g., WGBHDT2/3/4 can't
all have the same freqid, and there aren't even 4 programs being
reported by dtvstream in the first place), but what *should* they be?
Here's an example of the programs available on WGBHDT:
Stream contains 3 valid program(s).
Program 2: 2-1 WGBH-SD:
Video (MPEG-2), language = eng
Audio (Dolby AC-3), language = eng
Audio (Dolby AC-3), language = eng
Program 3: 2-2 PBS-HD:
Video (MPEG-2), language = eng
Audio (Dolby AC-3), language = eng
Audio (Dolby AC-3), language = eng
Program 6: 2-101 UpdatTV:
Unknown (0x0b)
