电影制片厂从DVD发售当中获得自己产品的大部分盈利，然而这个DVD会因为它数字化的天性被人们无限制地复制、再复制，而不用付出任何费用。

Film studios make the majority of revenues from DVD distribution of their productions, but that same DVD, because of its essentially digital nature, can be copied and recopied endlessly, at no cost.

对制片厂而言，电影数字化或卖给有线电视运营商作视频点播(VOD)用，利润更为可观。

For the studios it is much more profitable to stream a film digitally or sell it through a cable operator as a video-on-demand (VOD).
