  1. Newbie question: when I encode DV video to DVD, should I turn on deinterlace? The DV video is interlaced.

    Thanks!

    If you wish to view the output on a TV, leave it interlaced. If you are only ever going to view it on a computer, then deinterlace.
    If in doubt, Google it.

    What if I have a progressive DVD player and TV?

    I don't know to be honest.

    Progressive-scan DVD players add an important additional step to create a better-looking picture they generate a progressive-scan video signal through a process called de-interlacing (sometimes called "line-doubling"). The de-interlacer's first task is to look at the interlaced video signal as it leaves the MPEG decoder and determine whether its original source was 24-frame-per-second film or 30-frame-per-second video. The original frame rate determines the type of processing necessary to create an optimized progressive-scan signal.

    So if you de-interlace you throw away half the fields reducing what can be used to optimize the picture.

    NO!

    Your tv and DVD player will handle the video. You don't worry about that. It does the work for you. Leave it interlaced.

    "Progressive scan" is not progressive.

  8. Thanks! I guess that is probably why the progressive m2v file looks off.

  9. One more question: which media player is good for playing back interlaced mpeg on PC? What about playing to TV (nVidia card)? Will it look bad?

    Thanks!
