text subtitle colors does not work!?

Hi
I'm using dvdauthor 0.7.0 on fedora 14 and i have a problem:
I'm trying to use fill-color or outline-color with my text subtitle 
setting file. Spumux runs and do the job with no error,
but my result mpeg subtitle always has white fill-color with black 
outline-color !?
Is this a bug or something related to fedora packages?
this is my xml:
<subpictures format="pal">
<stream>
<textsub filename="Shrek.Forever.After.2010.utf8.srt"
                 characterset="UTF-8"
                 fontsize="29.0" font="nazlib.ttf"
                 fill-color="#FFF000" outline-color="#000000" 
outline-thickness="3.0"
                 movie-fps="25" subtitle-fps="25"
                 movie-width="720" movie-height="574"
                 horizontal-alignment="center"
                 vertical-alignment="bottom"
                 left-margin="60" right-margin="60"
                 top-margin="20" bottom-margin="30"
                 force="yes" aspect="16:9"
     />
</stream>
