Cables are your enemy. Your secret weapon is the Belkin FlyWire ($1,000). Operating in the open 5GHz band, this system wirelessly transmits high-definition 1080p video and audio around your house. This means that you can hang your HDTV on a wall and store your components (Blu-ray player, Wii, DirecTV receiver, etc.) out of sight in a closet or cabinet. The FlyWire offers 3 HDMI inputs, 2 Component inputs and 1 Composite input.
