Your losing me,
My screen is a 2.35 design, so 2.35 movies take the full width when I add the lens. Other movies stay the same height, but the black space/bars on the sides varies, depending on the material. Theatertek automatically adjusts for different aspect ratios and you can even setup custom ratios. So while your watching the intros/trailers/ and finally the main feature, you just sit back and enjoy the software does the rest. It automatically detects the AR on the DVD. I never mess with my Zoom/Lens shift unless the kids have been running upstairs and knocked my Z2 out of alignment.
