I can't understand why RealNetworks is introducing new software that lets people copy a DVD to the computer. The software is loaded with rules and limitations (more on that in a minute) and pales in comparison to free products out there. The product, called RealDVD, is presumably intended to beef up the weakest prong in RealNetworks' three-pronged product strategy. Music and games sales consistently outperform the media software and services side. But unfortunately for RealNetworks, RealDVD is too little, too late. Investors reacted to the news with a collective shrug. RealNetworks shares are unchanged in trading Monday at $6.19. RealDVD costs $50 (though it's on sale now for $30) and will make a digital copy of a DVD. Sounds like something that would throw Hollywood in a tizzy, right? RealNetworks is hoping to avoid any legal drama by locking down the movies so they can't be shared; a movie will only play back on the original computer. Actually it can be played on up to five more computers, but you have to buy another copy of the software for each computer. Once you get the movie on the computer, you can't burn it to another DVD. Maybe if this had come out years ago, it would have stood a chance. But there are plenty of free programs that do the same thing without all the rules (MacTheRipper, for example, is ridiculously simple to use). The big difference is that the legality of those free programs is in question, while RealDVD, at least for now, is legit. RealNetworks says the software is ideal for consumers and travelers (although I don't see why travelers can't just bring a DVD with them). Again, a little late. There are too many other ways to get movies on the PC now. Rent a movie through iTunes or Amazon. Find a free one on Hulu. Stream a video online with Netflix. Watch your DVR library with a Slingbox, or your TiVo library with the TiVo Desktop. It's a crowded field, and a $50 program choked by regulations will get buried quickly.
