Chad, are you sure you've got the widescreen version of the movie?
In my testing, you'll see the sharpest image with a regular (non-progressive) signal. The TV will take this and up-convert it to 1080i. It'll also perform automatic aspect-ratio detection and go into the proper viewing mode automatically (only works with a 480i input).
I love the image on my 46H83 (fully calibrated, of course). It's very detailed and very natural looking.
