<div>Thanks for the sample. It'll take some new development
to get this implemented in MythTV, but since ffmpeg seems
to understand the tx3g format, it should be doable.</div>

I used HandBrake to create the same sample in a mkv container and
mythtv can display the subtitles just fine.<span><font color="#888888"><br>

The subtitles in the sample display properly for me in mythfrontend, using Master. Most likely, this is a deficiency in the version of ffmpeg that was used with 0.25.</div>

Others confirmed that your sample does not show subtitles in either 0.25 or 0.26. This strongly suggests a problem in older versions of ffmpeg, but fixed recently enough that some ffmpeg resync for 0.27 has the fix (as does vlc). Presumably the older ffmpeg recognizes this subtitle type inside a mkv container but not mp4.</div><span><font color="#888888">
