At the moment the Detect Commercials is a blanket setting under Basic Setup. However in the UK several major channels do not have commercials, like BBC1, BBC2 and so on. For those channels, after recording, it still does the Detect Commercials processing, which is pointless, wastes CPU and sometimes detects commercials which aren't there.
It would be nice to have the Detect Commercials tick box on the Record and/or Series Pass windows, similar to the Padding options. Then those recordings would ignore the commercials processing completely.
