VGA and component should not make much difference in picture quality. 
Through the component input most TVs expect a HDTV compatible signal 
(1280x720 or 1920x1080i at 50 or 60 Hz) and not PC related resolutions. 
They also tend to have overscan on the component and HDMI inputs. I am 
running a NVidia card from DVI to HDMI on my Samsung LCD TV (native 
1368x768) and it does only 1280x720 at 50 or 60 Hz. I tweaked the 
modeline to have a perfect 50 Hz framerate (Netherlands PAL) which was 
not possible over VGA, so scrollers/newstickers/fast-motion now are 
buttersmooth with Bob-Deinterlace. It has some overscan though and I had 
to adjust the menu positions.
