This cable has made a noticeable difference while watching netflix. At first I did not see any difference then read that the screen resolution needs to be changed to 480p in the Wii preferences. After that was changed we saw a difference. While still not as good as HD on my TV it's much better. I think the Wii is limited to a max Res of 480. I saw some cables on ebay that were for 1080 but that does not make any sense if the Wii max output is 480. Does anyone know definitively what the max Wii resolution is? I'd like to know. Regardless; we saw a big improvement while watching the "24" series from netflix. With the original RCA cables the shading in the faces was very blocky and seemed to float like it was always 1 step behind. For instance when Jack would turn his head quickly it had a tracer like quality. Now while there is still some blockiness the block are MUCH smaller and the tracer effect went away. I don't know how to describe it any better
