This is why you leave the laptop at the back
Never use your own machine on stage. It will try to get you fired.
Give the PP file to the technical crew.
They will play it on their machine which is known to work, and you get a button to press that does nothing more than BEEP in the technician's headset.
And if you actually give it to the tech more half an hour before, they will have gone through it and made sure everything actually works.
And never, ever embed a video clip. The DRM will ensure that it does not work when you need it.
