for a starter, "-vf crop 720:480:0:0"
does nothing if you have a ntsc dvd that
already is 720x480. To remove the
telecined frames, you have to use "-vf
pullup,softskip", otherwise mencoder
will just drop frames at random to keep
the fps. If you still have some
interlaced frames left when using pullup
you can add the pp=l5 filter as well. It
won't remove the frames, but at least it
will make them less apparent.
