I had trouble finding these cables. They sold me a big sign of this type of products, "up" or cables red, blue green, saying he just had to find the correspondence between the white yellow red. Now this is quite different, the red green blue down the video signal into three color, without carrying the sound, while red carries the video and the yellow and white (I think it is in this the meaning, but check) carries stereo sound by right / left. Even in trying to make the exchange of these cables, the director kept me that it was equivalent, while obviously it did not work between my TV and my video player. Then looking on amazon, I finally found cables I needed, and for a price four times lower. The latter works very well, easy to connect long enough etc ... All is well! Thank you Amazon, why did I not try here first ??
