Well, this is because of the mpg demuxer (lavf works fine by the way).

Apparently the mpg demuxer can detect subtitles only while playing, but
MPlayer has already finished updating subtitle information then.

In order to really fix the cause, update_global_sub_size() should be called
prior to returning MPContext global_sub_size information. Unfortunately,
update_global_sub_size() cannot be static any longer then.

I consider this a better solution that adding some update_global_sub_size()
code to the GUI.

Opinions?
