The Scheduler and EPG only work if you set it before the TV program starts, and they take time to set, if you set it after the TV show has started, it will not record.
If you miss the start of your TV show, it would be very good to just right click on the record button to set the timer, and not have to input the start, stop time, and date
That way, if you record a 50 minute TV show, you could click 1 hour, and know it would only run over time by 10 minutes
, the stop recording
This would be like on the old VHS video recorders that had one touch timer record
