Using the Electronic Programme Guide and with the press of just one button, my STB can be set to record a programme. 

If the programme starts late and finishes late (almost always because of channel advertsing) will the EPG adjust the start and end recording times automatically?  Or must I always manually add an extra few minutes to the EPG settings to be sure not to miss the end of a programme - like I have always done when using G-Code on my DVD recorder.
