Talk about your market forces. Adult Film Studio Offers Downloads to DVDs:

On the business side, Hollywood makes more money offering films on DVDs than in theaters. As a result, studios are hesitant to anger large retailers such as Wal-Mart Stores Inc. and Blockbuster by selling DVD-ready downloads directly to consumers.

Recently, most of the big studios have started selling films over the Web, including on CinemaNow, which is partly owned by the film studio Lions Gate Entertainment Corp., Microsoft Corp., Cisco Systems Inc. and Blockbuster Inc. Consumers can burn a backup DVD, but it can only be played by a computer, not a DVD player.

The adult film industry doesn't face the same business challenges.
