Hooking up your home theater system can be a nightmare, and it only gets worse as you add more electronics. If you are not particularly tech savvy, you might not know the difference between an S-Video Cable and a Component Video Cable; don't worry, you are not alone.
The Consumer Electronics Association (CEA), the preeminent consumer technology trade association, has developed a Web site to help consumers hook up their home theater systems. The CEA Connections Guide is an interactive guide that lets you select which equipment you wish to hook up (e.g. DVR, Set-top box, TV, etc.). It then asks you to choose which components are available on all the equipment you had previously selected (e.g. S-Video, Component Video, etc.). At this point, you will be able to choose which equipment connection instructions you wish to view. Now that you have a detailed guide, hooking up your home theater system should be smooth sailing.
