Comment (by miguelapg):
Subtitles are positioned according to PAL dimensions by default, instead
of placing them at bottom center as VLC or MPlayer do.
Seems this was added at
http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=1fc20af6af3ec31d0ee665557885b6c20c6d3686.
Why VLC drop subtitles in the usual place (bottom center), and even scale
subtitles to fit video dimension, and ffmpeg doesn't do it?
I think that this feature is not finished if ffmpeg is not following the
standards of video industry, as ffmpeg is also a reference in the video
world.
I have attached an screenshot to show how subtitles are placed using a
common set of parameters (even recommended by ffmpeg guides) ...
-filter_complex '[0:v][0:s:0]overlay[vid]' -map '[vid]' -map 0:a

Mapg
