title: How to get LG LS3450 TV to properly show subtitles?
body: <p>The manual it should support mkv files with: Video: H.264 /AVC, XViD, MPEG-4 Part2 Audio: HE-AAC, Dolby Digital, MPEG-1 Layer III (MP3) Support .ass subtitles too. So what should i exactly do to be able to play this with the correct formatting and everything else?</p>
  <p>Converted the FLAC audio to AAC using this command:</p>
  <pre><code>ffmpeg -i CodeGeass01.mkv -c:a libfdk_aac -profile:a aac_he_v2 CodeGeass01_1.mkv
  </code></pre>
  <p>It plays, but without the custom fonts and the subtitle positioning not working either. So it seems i need to make a hardsub video, need to burn in the subtitles. and encode the audio to aac. so how do i exactly do that, with the correct formatting, positioning etc?</p>
