I agree 100%. The above command line would do a pretty horrible number 
on any kind of source I can think of. Here's a more common pullup for 
NTSC DVDs:

-fps 30000/1001 -vf pullup,softskip,yadif,harddup -ofps 24000/1001

(the yadif is in there to catch the occassional interlaced frame that 
might creep through from bad edit points on some titles)
