No.  Not as such.  The video container includes flags that tell the DVD
player which fields to repeat, when, and how often...  The typical 3:2
pattern.

MPlayer first sees the 29.97fps field set in the header.  Then, after a
few frames, it figures out that there is really only 23.976fps.

No, not unless you tell it to.
