How to hook up a DVD player to a Time Warner cable box

[ltswagg]

I have a Time Warner cable box and a Sony DVP-SR500H DVD player. I'm trying to hook up the RCA cables that I do have which is red, white and yellow. It didn't work. I noticed the cable box has other colors like green and black on the back and my DVD has a green slot. Do I need to buy extra cords? I also have an old big tv from the early 90's. Thanks for help!

Most cable boxes do not have inputs only outputs. If the cable box is connected to the only video input on your TV you will need to get an AV switcher.
