Yes, but the sample.mov is incorrect in that it is tff but the frames
acording to ffprobe are top_field_first=0.

Testing with yadif=1:parity=tff produces a working result.

I guess idet manages to by luck or design to tell w3fdif tff.

Thare may be another way to do this - but I don't know it.

AIUI DV* is specified as bff, so I guess this sample was not direct from
a camera but has been coded from elsewhere?

@Carl Eugen, while testing I notice that mplayer has a u/v reversal bug
for raw422p, though IIRC this is known - mentioned just in case I
mis-remember.
