I used the THX optimizer that was included with Star Wars EpII. There was a geometry section that showed different sized rectangles and circles for the different aspect ratios to ensure that the picture was centered and square. My picture was nice and squared, but it was shifted to the left...
Andy - I did a very basic calibration (if you can call it that) with the THX optimizer on my HS510 and I noticed that during the geometric calibration the screen seemed to be shifted to the right. Did you see this? Any idea how to adjust?
