dvd-pal target does not force correct colorspace (with DVCPRO50)

Description

When encoding DVCPRO50 material (or most likely any material having non-dvd-conformant chroma subsampling) to a dvd as in

ffmpeg -i dvcpro50_sample.avi -target pal-dvd -b $vbrate -minrate $vbrate -maxrate $vbrate -acodec ac3 -ab $abrate -flags ilme+ildct -threads 2 dvcpro50_sample.vob

the resulting vob has a yuv422p colorspace.
Authoring with dvdauthor and playing the file on a standalone player results in a colorful puzzle instead of the correct picture.
No errors whatsoever in the authoring process or when viewed with mplayer, vlc, etc..
I guess
-pix_fmt yuv420p
should be forced with the meta parameter -target <whatever>-dvd
