Composite versus Component – Twilight Princess Teaches All
Heard about component video but haven't the slightest idea what it is? You're probably not alone. The Nintendo Wii ships with a set of composite cables, the familiar red, yellow and white cords that plug into most VCRs, DVD players and television sets. Those are fine and produce a much clearer picture than, say, a co-axial cable. However, component video ups the ante a bit more with a better picture and improved sound.
Don't believe me? This side-by-side comparison video from GameVideos.com shows the full intro sequence to The Legend of Zelda: Twilight Princess in both video forms. You can see component video produces a slightly sharper picture than the composite. It isn't a difference you'll cry about as you fall asleep at night, but every bit of beauty you can pump out of your Wii system will definitely be appreciated.
