So, I'll take these cables back and get the right ones
If you need to. Depends on whether you need 5 or 3 RCA in total and if the one you bought actually has one higher quality video cable attached along with the two audio cables.

If you only need 3 in total ( 1 video, 2 audio) check to see if the yellow one seems to be a bit thicker or stiffer than the other two.. may have some faint writing on it as well indicating it's a video cable)
