After installation, I do not regret !!
With the RGB image shimmered and became very blurry when traveling. Since then, with the YUV cable, finished flare and blurred. The picture is perfectly clear! Of course, this reveals aliasing, especially on a TV 47 ", but hey we should not forget that the Wii is not an HD console.
A therefore recommend for those who wish to enjoy their console on their LCD!
