I didn't mean to say that I can all that clearly see the pixels at my normal viewing distance while watching a movie, just that I can see some more than I expected/hoped. It doesn't have an LCD screen door effect or anything and I'm mostly seeing such clear edges by viewing sharp non-moving text/images, like a desktop or menus of a PS3. I'm sure I'm projecting larger and closer than any THX spec would recommend, but that still doesn't mean that a 1920x1080 resolution that barely cuts it for a desktop monitor is going to look all that great at 150", especially viewed at 10 to 16 feet away, nothing short of a higher resolution projector would do a lot to address that.
And I just checked again, the dark spot starts at about 2:29, it begins being visible on the nose of the star destroyer and it moves along (well, the star destroyer moves) until it gets to about the main hanger on the bottom before they cut away to the star destroyer getting a shot in at the main reactor of the Tantive IV.
