Not for most duff you mentioned, but the adbreaks themselves:

Our old dvr enabled us to skip ads in the recorded tv programs pretty accuratley. It set chapter markings whenever an ad-block began/ended which it figured out by the frequency of hard cuts as ads have them between every ad (so multiple times a minute) whlie normal programming usually does not. This was way pre-AI (like late 00s). Sadly the built in dvrs in our tvs after that did not have that function, but maybe there is a modern implimentation somewhere.
