[mythtv] HDTV doc diff for channel settings

This is a great improvement. But a couple nitpicks...

* The frequency part of the "freqid" can be any channel starting at 2,
  in my city there are a couple ATSC stations on channel 12.

* It is recommended to the broadcasters that they don't change the
  program id's often and that they never use program id 1. This is for
  faster tuning, and for compatability with DVB which uses program id 1
  for the Network Information Table. If you are using a freqid such as
  "44-1" and it works, this is only because MythTV tries to guess at the
  program id if you got it wrong, and often guesses correctly.
