Commercial detection can be set at 3 levels:
- Globally, for all recordings
- If globally enabled, specific channel numbers can be selectively ignored from detection
- Regardless of the global setting, commercial detection can be enabled/disabled on a per-program basis
I was referring to the specific programs' setting for detection, as that is separate from the global setting.
(There is also a fourth condition, but it must be manually done via the command line: certain categories can be ignored for detection, such as disabling detections for all recordings marked as "Movie". But, I would think that if you did such a thing, such as enabling detection for "News" regardless of global setting, then you would have remembered.)
