subtitles in transcode aligned with top of screen

tested on 1.2 nightly 31/dec/2011 tested mac and pc

when subtitles do load, they are displayed at the top of the screen rather than the bottom

when viewing the same file in the normal UI, the subtitles do correctly align with the bottom

-sub-margin -xxx can be used to move the subtitle down, but that requires you to know the height of the movie. (and a top default is inconsistent with the normal display)

I'm using this transcode command

"VLC" --ignore-config -I dummy -vvv "/Movies/file.mp4" vlc://quit --sout='#transcode{vcodec=h264,soverlay,acodec=mp3,channels=2,venc=x264{profile=baseline,level=2.2,keyint=45,bframes=0,ref=1,nocabac},width=400,fps=25,vb=200,ab=60}:std{access=livehttp{seglen=10,index="/Stream/file/stream.m3u8",index-url=stream-###.ts},mux=ts{use-key-frames},dst="/Stream/file/stream-###.ts"}'

(file paths shortened for clarity)
