If course the patch doesn't care about the movie aspect from the file;
actually, mplayer's design architect is way smarter than that.
When subtitles are rendered, we are given two params, dxs and dys,
which describe the size of the area we have now, _after_ all filtering &
other operations. And we have the original frame size of the vobsub...
So it would be really hard to get it wrong.
Anyway, see my screenshots posted earlier thie afternoon.
