Not that you'd win anything if it did work. mcdeint in general (as well
as yadif=3) _only_ makes sense when you double the frame rate, i.e.
-fps 25 -ofps 50. Since dv can not store that (I think) yadif=1 is about
the best you can get - which is still lower quality than storing the
interlaced video in DV and doing proper deinterlacing on playback.
