That's right. It's deinterlaced first, then each field is scaled (doubled) to 480. They *are* offset vertically from one another, so positionally it looks right. You'd get a slightly sharper static picture with kerneldeint, but motion is so much smoother with bob it's my first choice. The only advantage to using a true 480i mode would be if your set's deinterlacer does a nice job (which the Sonys do) but I never got it working right with the nVidia drivers at the time. > My current TV automatically switches into a "vertical squeeze" mode > when it receives anything higher than 480p.
