Despite Start live detection when watching in-progress recording being unchecked in the DVR settings, live commercial detection (Comskip) still ran on a recording after it was cancelled, instead of running in normal "non-live" mode (live=0) like it should have.
The Simpsons S34E02 was scheduled by a Series Pass with 30 minutes of end padding (in case a sports event runs late) and 10 seconds of start padding, so 7:59:50pm–9pm. At 8:30pm, I briefly played the in-progress recording from the Web UI and verified the show had ended on-time by skipping to the end. At 8:42pm, I used the Recording dropdown > Stop Recording option on the Schedule page to cancel it.
