Hey Nanu.. From what it sounds, The white leaded component cables that you have are uselss (the ones the came with the hauppauge). The only other thing you could do, is to buy another set of Hdmi to component cables to go from your ps3 via hdmi into the hauppauge(with component) then from the hauppage (component) into ur tv (HDMI).. either that or use it on another tv =/ and i dont think that hdmi to component downgrades the quality, right now im using components and it looks just like hdmi
