You are lucky to live near a Cineworld as my closest 1 is about 50 miles away, so by the time I have paid the train fare to get there, the price of the card isn't worth it.
I have no problem in paying for the cinema, however if I go to the cinema & enjoy the film, then I will obtain an R5 or screener & then purchase the film when it gets released on disc. For instance I will be obtaining The Expendables after I have seen it at the cinema, so I can see it again with the scene that got cut from our screens.
Getting back to topic, I don't think that Hollywood is winning the war against piracy as more & more people have divx capable devices now, should it be a dvd player, HTPC, or games console like 360 & PS3. Also considering that you can get 1.5tb external HDD for under
