You are using a composite cable, which is the lowest quality of connect for the video and audio. You PS3 has an HDMI cable output, purchase yourself an HDMI cable and you will see a better picture and sound. That is if your tv has an HDMI cable input, if not you should have a component cable input. It is 3 rca jack in 3 colors for video and an optical input for the digital sound. Hope this will help you out.
