Ouch.  Please pretend I didn't post this.

Detecting a change in the major_channel_number field would have the same
effect, and the major_channel_number also usually appears on the screen
when the "INFO" (or similar) button is pushed.

Still, I doubt most DTVs bother to monitor this for changes unless the
viewer initiates a scan.
