Any way you look at it it's bad DVD authoring. If the source is 60i then it could at the very least have been "1:1" on the NTSC DVD. Dunno how or why they cocked it up, but it seems riddiculious when you think about it. Even if the effects shots were done at 60i it isn't that hard to bring it back to the original 24fps. If absolutly necessary, just re-do the effects. Anyhow, I stand by what I said, it isn't too hard to remove field-blending using automated, so long as you isolate the "effects" shots. :)
