         Although the source material is obviously computer-generated,
         the rendered-output is 24fps progressive.  Hence, the
         video-sequence can be treated as a 24fps film source.

         The MPEG-2 video is coded as an interlaced sequence,
         with NTSC 3:2 pulldown.  Coded picture rate : 29.97Hz

Conversion:

  mpeg2avi.exe -b source.vob -f0 -r -s4 -2 -1 352 240 -o7 IVTC.avi
  mpeg2avi.exe -b source.vob -f1 -r -2 -1 352 240 -o7 raw.avi

  (FPU-IDCT, half-resolution output, crop to 352x240)

  encoding time was ~11min on a Celeron-450, Win98SE
  no audio, Microsoft MPEG-4v3 @ 600kbps, 1keyframe/s, sharp:100

  The *_raw.avi file is a straight MPEG2->AVI transfer.  The
  resulting AVI exhibits hairline weave artifacts due to the
  source M2V's hardcoded 3:2 pulldown.  The rawAVI's frame-rate
  is 29.97Hz, to match the source M2V's playing time.

  The *IVTC.avi file is the same M2V->AVI transfer, but with
  the inverse-telecine algorithm (-s4) enabled.  The IVTC.avi
  file has 20% fewer frames, and therefore plays @ 23.976fps.
 
  (Please note that the compression artifacts are a result of
   severe video bitrate reduction, not the IVTC process!)

Notes:

  DolbyDigitalBroadway.vob starts as a 3:2 pulled sequence.
  Toward the end (the shimmering light logo) the source
  changes to 30fps video (2:2 pulldown.)  Due to the presence
  of both content types (24fps film & 30Hz video), this clip
  cannot be inverse-telecined.


  *For playback to be smooth, CPU should be very fast ( >300MHz.)
