Even though this issue seems to be resolved, I thought I'd chime in with a technical note.
Assuming that “DVD” means a VIDEO_TS folder on a NTSC DVD-Video disc or other DVD media, the video format is multiplexed MPEG2. If the MPEG2 video stream conforms to DVD spec, then it is 480i60.
If the goal is to use the extracted video as source in a video edit, one could make a strong argument for converting the MPEG2 stream to a format for editing that is also 480i60. DV-NTSC and DVCPro50 are perfect candidates as they both support 480i60. Also, custom Apple ProRes settings could certainly be put to use. Basically, keeping the frame size, field rendering order and frame rate consistent are key to getting a good conversion.
MPEG Streamclip, DVDxDV (both mentioned in prior posts) or Toast will do this type of conversion well.
If the file is just being extracted for playback on the desktop or a mobile device, then the MPEG2 stream could get converted directly to a M4V, MP4, or H264 movie (adjusting frame size, de-interlacing, and adjusting frame rate as needed for the intended playback device).
Handbrake (http://handbrake.fr/) will do this type of conversion well.
For what it’s worth,
