I have searched all over for about 3 days trying to figure this out. Here is my setup. My dvd player(xbox) is connected to my tv with component connections. I then have composite cables connected to my computer from the tv-out jacks. When I load up my capture software (Giga Pocket, came with PC, Nvidia 5200 card), there is no sound signal and the image is black and white (yet clear). When I connect the xbox directly to my pc with composite cables, It works fine.(sound, color) Or when I connect the xbox to the tv with composite, instead of component, then then connect the tv tv-out to my computer tv-in with composite, it works fine. This downgrades the image/color quite a bit. (component>>>composite) This leads me to believe that the problem lies with the component input into the tv. Any help would be greatly appreciated.
