Patch to fix the duration computation of output buffers

The current code sets the output buffers duration to a negative value! The
attached one-liner fixes that:

2006-08-05  Frederic Riss  <frederic.riss at gmail.com>

        * gst/dvdsub/gstdvdsubdec.c (gst_send_subtitle_frame): Unless
        we're playing 'Back to the future', we'd better use positive 
        buffer durations.  

With this patch, I'm able to display the subtitles in an empty window using a
pipeline along the line of:

gst-launch-0.10 <src>  ! dvdsubdec ! ffmpegcolorspace ! xvimagesink

where <src> is either a dvddemux on a vob file or a matroska demux on a
matroska file embedding VOBSUBs with my patch in bug 343348 applied.

I still don't manage to build a pipeline where I use videomixer to mix the
decoded video with the subtitles... Possibly related, subtitles still don't
work in totem. So where should I look next to make all this working ?
