Hi ereed,
There is no inherent superiority in picture quality to HDMI/DVI connections, despite the hype that surrounds HDMI/DVI. The latter are digital connections and involve complex digital anti-piracy "handshaking" which uses up valuable bits that are not devoted to video processing.
Component video connections are analog and fully capable of passing HD video with none of the HDCP digital handshaking baggage.
Depending on your display, component video may deliver picture quality superior to HDMI/DVI. However, if you have a 1080p display, only HDMI/DVI will pass a 1080p signal from 1080p-capable formats (HD-DVD, Blu-ray, etc.).
Try the component video and HDMI/DVI connections and use the one that produces the best image quality, if a difference is visible.
Regards,
