[MEncoder-users] Does -ass work with mencoder?

[Pepe]

MPlayer 1.0rc1-3.3.4

I play a video with this options:

mplayer 3x15.avi  -sub 3x15.srt -subpos 98 -subwidth 80 -subcp latin1 -ffactor 
1 -fontconfig -font arial -subfont-autoscale 1 -subfont-text-scale 6 
-subfont-blur 0 -ass 

The -ass option is working because I can see the yellow subtitles.

Now I do:

mencoder -noodml -o atlantis315.avi \
  -oac copy \
  -ffourcc DX50 \
  -ovc lavc \
  -lavcopts 
vcodec=mpeg4:vbitrate=970:mbd=2:vstrict=1:vmax_b_frames=2:vqmax=16:v4mv:trell:vb_strategy=1 
\
  -vf-add harddup \
  -force-avi-aspect 16:9 \
  -sub 3x15.srt -subpos 98 -subwidth 80 -subcp latin1 -ffactor 1 \
  -fontconfig -font arial -subfont-autoscale 1 -subfont-text-scale 6 \
-subfont-blur 0 \
  -ass  \
  3x15.avi

The subtitles of this video are white. I tried with -ass-color FF000000, in 
mplayer that gives red subtitles, but in mencoder the subtitles are still 
white, so I think the -ass option is ignored.

Why?
Is this a bug?
