For the record, this what I've come up with so far.

Playing pal-dv at double-framerate with mplayer:

$ mplayer -mc 0 -nocache -field-dominance 1 \
    -vf yadif=3,softskip,scale,harddup input.mov

Transcoding pal-dv at double-framerate to spal:

$ mencoder -mc 0 -noskip -vfm ffmpeg -sws 10 \
    -fps 25 -ofps 50 -field-dominance 1 \
    -vf yadif=3,mcdeint=1:1:10,softskip,scale=::::::spal,harddup \
    -aspect 4/3 -of lavf -lavfopts format=mov -oac pcm -ovc lavc \
    -lavcopts vcodec=mpeg4:vqscale=2 -o out.mov in.mov

Feel free to correct/improve.
