One more thing. My HDTV says it can display 1080i. What does that mean if the native is 720p? Does that mean it just takes a 1080i and scales it to 720p? (Display is technically 1386x788).

I'm soooo confused.....
That is correct. Your TV will take a 1080i signal and deinterlace and scale it down to 720p. Your choice is then whether to leave your HR20 set at Native (and allow for the extra time to switch resolutions as it changes from source to source - 480i for standard def stuff, 720p for Fox, ABC, EPSN, and 1080i for CBS for instance) or to tell the HR20 to do the scaling by turning Native off and selecting an optimum output resolution.

In my case, my TV is 1080p and can accept and scale all the standard input resolutions - 480i SD TV, 480p from a progressive-scan DVD, 720p, 1080i . . . however I haven't really seen much difference between the TV's scaler and that of the HR20 on D* content, so I just leave Native off, set the HR20 to output everything at 1080i and let my TV deinterlace the signal for display. It generally looks great.
