Sales people claim that the RCA/phono cable labeled "audio" will not work for carrying video a very short distance (less than a foot). The "audio" cable will be used to interconnect two yellow-colored "video" RCA/phono cables. My concern is video picture quality will look much worse than if expensive cables labeled "video" are used.
Similarily, is there a difference between the yellow and red/white/black connectors ?
I'm sure the AV-philes will cringe at this, but in most situations, a RCA cable is a RCA cable is a RCA cable.
There is no difference, electrically, between the red, white and yellow RCA cables. The color coding is just to help you make sure you keep your cables in the right order.
However you may also notice that there are component video and coax audio cables which also use the same RCA connectors. While these cables use different colors as well, they are still basically the same as the good old yellow, red and white cables you are familiar with. These cables will have slightly better electrical properties, but for short runs you can often get away with just any RCA cable.
