[MPlayer-users] Using .sub-Subtitles in mencoder possible?

[Thomas Heuving]

I'm using mplayer SVN-r29134-snapshot-4.1.
When I play an avi with accompanying .sub- and .idx-Files, mplayer says:
  SUB: Could not determine file format
  Kann Untertitel nicht laden: ./love_in_a_fallen_city.sub
but the subtitles are shown.
If I want to resample the avi to put it on a Video-DVD, I 
get just the same message, when I give the .sub-File to mencoder
with the -sub-Option:
  SUB: Could not determine file format
  Kann Untertitel nicht laden: love_in_a_fallen_city.sub
but there are no Subtitles in the output.

How can I produce a MPG-File, in which the Subtitles are included in
the Videostream?
The complete Commandline of mencoder is
  mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd -ofps\
  30000/1001  -vf scale=704:464,expand=720:480,harddup -lavcopts\
