The video itself is indeed stored interlaced, even though the camera
was shooting full frames. There are no 'repeat field' codes, so
mencoder/mplayer won't sync to them, and you need to use a filter.

I'd suggest -vf pullup and -ofps 24000/1001 on whatever you are trying
to do.  Thats somewhere to start, and ive verified that -vf pullup
does give you the proper 24fps non-interlaced result you seek.
