These days, gratuitous sex scenes, foul language and violent extravaganzas are a given in the world of movies. Understandably, most parents are concerned with the effect such raw stuff has on their children. That's where www.cleanflicks.com, a video-editing company, and its rental outlets, CleanFlicks, come in. CleanFlicks stores rent hundreds of videos that have been edited to make films more "family-friendly." Jason Smith, manager of the Englewood store, likens the finished product to edited network-TV flicks: not much nudity or cussing, maybe a little violence. The stores, which are adding edited DVDs to their rental stock, receive about 25 new titles every month. Move over, Disney.
