So far I have only been interested in DVD and transfer of home movies to DVD. Divx is fairly new to me. Therefore I apologize for the probable stupid nature of this question: I've visited the Divx site and found out you could rent Divx movies and view them as they were downloading from the website. As it is possible to record streaming video from real or quicktime, how do they prevent you from recording the Divx download and making copies of it? I know this may be awfully stupid question. Spare me the giggles and give me a simple answer for my simple mind. Thanks.
