I use a Sanyo Z2 WXGA projector with native 720p via component and HDMI/DVI from my Panasonic S97S player. The DCDi Faroudja scaler on the Panny is better than the scaler on my Z2, so I turn my onboard projector scaler off and let the DVD player handle it.

To answer your question based on my experience, I do notice a difference using HDMI at the 720p/1080i modes versus standard 480p over component. Just my 2 cents.
