Include the ability to edit out unwanted features from a movie such as adverts and bootleg warnings

I purchase all my movies and really hate having to watch those pre movie trailers that firstly show you a short vidfeo about not buying bootleg videoa then have to watch several mnovie trailers. I want to get down to the nitty gritty right away. Being able to edit these out before burning a back up copy would be brilliant. Thankyou
