My DVD is NTSC. Flask says it is interlaced, but when I open video options tab, "reconstruct progressive images" is checked. I tried unchecking it and checking deinterlace video with threshold of 5 and with 10, but the final video did not run smoothly. I finally left "reconstruct progressive images" checked, so that flask said my input was interlaced, and output progressive, and the video ran perfectly! Anyone else use this setting? Does this make sense?

Thanks,
Rick
