I know this has been covered (sort of) before.. but...
The only difference I can see is between "interlaced" (screen is shakier because of the every other line thing) and the other two... but I want to know... do any of the 3 actually change the resolution of the picture? Is "interlaced" 1080i and progressive a different resolution?
thanks

I believe that DRC (Digital Reality Creation) is Sony's moniker for 2:3 pulldown.

The interlaced setting changes the resolution and upconverts it to 960i, progressive and cinemotion stay at 480p.And cinemotion uses the 3:2 pulldown.
Hope that was helpful.

Digital Reality Creation™ (DRC) Multifunction Unlike conventional line doublers, the DRC Multifunction feature replaces the signal’s NTSC waveform with the HD equivalent, while doubling the number of vertical and horizontal lines. This results in four times the density for quality sources, such as DVD, satellite and digital camcorders. The Video Menu allows you to select interlaced, progressive or CineMotion™ output.
• CineMotion® using the reverse 3-2 pull down technology, the Cinemotion feature provides smoother picture movement when playing back movies or other video sources on film.

I guess specifically, what does it do for a high def. source? Does the tv default to 720p or 1080i based on the broadcast itself, does DRC have any effect on a high def. signal?
It doesn't do anything for HD, only SD. This is called "upconversion". All HDTVs have this in one form or another, with varying degrees of "results".
