Can someone tell me why the entertainment industry insist on releasing films on triple play blu ray - so you get a blu ray, a dvd and a digital copy? The digital copy I can understand, but if you have gone out and purchased a blu ray player, why would you then want a standard dvd as an added extra with the film? Is the industry just trying to use this marketing ploy as the excuse as to why blu ray discs are twice as expensive as standard dvd's?
