VLC doesn't auto-load subtitles if file loaded through http interface
tested mac os 1.1.3 (4th Aug nightly) also 1.1.2 mac os and 1.1.1 windows
if you open a file with the standard interface, then vlc auto-opens any subtitle file with the same name from the same folder
e.g. open /movies/somemovie.avi and vlc will open the subtitles /moview/somemovie.srt
if you open /movie/somemovie.avi through the http interface, then you don't get the same behaviour (no subtitle file is loaded)
