Digital technology and large screens make for an amazingly satisfying film experience. Not as satisfying as the big screen, but much more satisfying than any other technology substitutes (ie tv reruns with commercials, or videocassettes with regular tv). And once you've invested in the technology, the cost of renting the DVD (which can be watched by a lot of people at once) versus the cost of a night out at the cinema, is pretty considerable over time, when you love films and watch them a lot.
