I feel that an HD feed from my Satellite receiver does looks demonstrably better via HDMI than a Component Video feed to my 50" Panny Panel.
With my DVD player, component is just as good...BUT my DVD player is not an HD unit. Artifacts on panels being what they are, I'm willing to bet that HDMI from the HD DVD will be the way to go- keeping the signal in digital domain all the way to the display.
