It looks like a field order problem. NTSC video is field-based at 60 fields per second. The odd and even fields combine to create a full video frame at 29.97 fps. If you capture with the wrong field order, it plays back the wrong field first, which is really obvious with any horizontal motion. DVDs retain the same field order format, so they're directly compatible with your standard television. So somewhere along the line your field order has been switched. You could deinterlace your video before export, which you would want to do, only if you're creating a video for playback on a computer or on the internet. That's because your computer is a progressive scan display. All lines are played on each frame. NTSC television is interlaced with the odd and even lines played back in separate field scans.
