Yes, I understand it's very difficult to determine if the *video* is
interlaced or not.. 

I meant that mplayer would print if the input stream consists of fields..
for example mpeg2 can be interlaced or progressive..

also at least dv avi is interlaced usually.. while mpeg1 and mpeg4
(divx/xvid) is usually progressive.
