Yet another reason to avoid the Battlefield Earth DVD: A brand new "feature" called Regional Coding Enhancement, or RCE. Having the word "enhancement" in the title might make us think that we, the consumer, might actually benefit for this technology, but that isn't the case. The only people who will benefit are the movie studios. Thanks to RCE, if you own a region-free DVD player, guess what? You can't play Battlefield Earth on it.
