If you're getting more than 2 or 3 skipped frames, it probably means
you picked the WRONG -ofps value, so it's good that it's printing
them. BTW the correct value for inverse telecine is 23.976, not 23.98.
Shouldn't make too much difference though. But if you're getting lots
of skipped frames with that, it's very possible that the movie is NOT
telecined but rather full NTSC (29.97) or PAL (25) framerate. For
example, US television shows converted to DVD will really be 29.97 fps
and you should not use -ofps with them like you would with a
theatrical movie converted to NTSC.
