So my buddy convinced me to take my 99%mkv library and convert it to m4v for home sharing in iTunes. Which is great. I pull the mkv apart using mkvtools, then remix it into mp4 with the video, audio, and subtitle track. Playback in VLC to verify it works. Put it into iDentify which tags it and throws it into iTunes. Great. Wrong. I can't get any frickin subtitles to work. VLC confirmed the subtitle is there but iTunes doesn't like it. Any ideas????
