Answers.Text: Note that the flags in the file don't necessarily reflect what's in the video.  Badly-chosen encoder settings could for example encode progressive content as if it were interlaced.  Output looks the same, but the encoder would be assuming that odd/even lines are from different times.  (small loss in quality per bitrate.).  Or, interlaced content encoded as progressive.  Probably a large impact on quality per bitrate in this case, the encoder would see the combing as detail that it had to preserve the normal way.  (I doubt any encoders auto-detect combing and enable interlaced mode.)

Answers.Text: Also, DVDs can switch from soft to hard telecine mid-stream (e.g. the Star Trek DVDs do this, since the effects shots were done with video equipment, but otherwise the show was filmed at 24p.)  If Mediainfo only looks at the beginning of the video stream, it would miss this.

Answers.Body: <p>You should be able to tell just by looking at it.  When you watch for motion and see a comb-like horizontal pattern, the video is interlaced.  You could also try pausing the video at several points and looking for this pattern, but not every frame will look interlaced.  Pause the video at points where there is quick motion, and step forward one frame at a time.  Make sure the video is displayed at %100 zoom.

Answers.Text: If not every frame of motion has combing, and the pattern is 3 progressive, 2 interlaced, you probably have a video that was telecined to 30fps from 24fps, with a 3:2 pullup.  Normally 24fps video just gets stored on DVDs as 24fps progressive, and the decoder can telecine if needed (soft telecine).  But sometimes you see video that was hard telecined, and the 30fps TC output was sent to the encoder.  Star Trek DVDs had mostly progressive mode, but their effects shots were done with 30fps NTSC TV equipment, so segments of each show are hard TCed.
