Nero essentials is a very limited program to begin with. Without knowing what version of Nero your using it’s hard to know where to start. Also that torrent movie have you tried to play and watch it from beginning to end?? How are you burning at what speed and firmware of the drive also what media are you using? What are you playing it on that it won’t play? There are alot of questions to ask about specs to be able to know what is going on there with your dvd burns?
