MATTHEW SCHULZE, BLACK RIVER FALLS, WISCONSIN: Hello my name is Matthew Schulze. I'm from Black Rivers Fall, Wisconsin. And my question is: How are DVDs made?</s>RICK LOCKRIDGE, CNN TECHNOLOGY CORRESPONDENT: Well, DVDs are like CDs on steroids. They work the same way. There are little pits etched into plastic. Those pits represent ones and zeros. But they are much too small to be seen by the human eye. And so a special type of laser beam has to read them. Now, unlike CDs, which can only hold about 650 megabytes worth of information, a typical DVD can hold seven times that much. And some types of DVD can hold even more than that. And that's why you can get an entire feature-length Hollywood movie on one DVD disk and still have room left over for directors' comments and interviews with the stars and things like that. There is also a type of DVD recorder that will essentially -- some feel -- replace the VCR. You can record programs off the air just the way a VCR does. But the movie studios are really against that technology because they don't ever like it when consumers make a perfect digital copy of their work. So we're going to have that whole argument over again that we had back when the Betamax came out: How should consumers be allowed to copy -- or should they be allowed to copy movies and other entertainment for their home use?
