The industry aren't losing any money from me, as if I didn't have a pirate version I wouldn't pay to go to the cinema (full of noisey little oiks) or buy an extortionately priced dvd, I'd wait til it was on sky. However, they may well gain money from me as if I like the film (that I wouldn't ordinarily have seen) then I'll buy the legit version when it eventually becomes available.
The industry also does themselves no favours by releasing different versions in different countries. I wanted to have the full uncut Cronicles of Riddick, but the powers that be decided that we could only have the Disney version, so what options do we have apart from importing a region 1 version or buying pirate?
Bring down the cost, release the same version at the same time in all countries, shorten the gap between cinema and dvd and piracy will reduce greatly.
