Yes, sorry, the switch that really makes both interlacing and
telecining disappear is
 -vf pullup,pp=md. and I could not see any difference with softskip.

The complete command I used was:

mencoder -vf pullup,pp=md,harddup -ofps 30000/1001 -ovc xvid -oac
mp3lame -xvidencopts bitrate=-300000:turbo:pass=1:profile=asp5 -o
tmp.avi [vob file]

(of course with another one with pass=2).
Another unrelated problem I had was that my DVD player (philips DVP
642) seems very picky, and I read somewhere that specifying a profile
(asp5) and hard duplicate frames (harddup) would help. It turns out
it's not enough... Anyway, I need to experiment more before I ask.

Thanks anyway!
