Review title: "Home Video" is a misleading title for this book. Product review: Incredibly, he completely avoids AC3, Dolby Digital, DTS, component video, and similar areas I hoped to learn about. The rest of the book was either overly technical or uselessly vague. This author appears to know little about home theater and a lot about ham radio. It's a poor quality book, and I wouldn't expect this from McGraw-Hill.

Review title: Great alternative to expensive Xbox controllers! Product review: I am a trackball fanatic when it comes to my desktop, however playing FPS games was getting quite tricky. I bought this controller as I got sticker shock from the other controllers out there. It works just fine and the controls are just like that on the name brand product.
