I have some .sup files from an NTSC DVD and want to use them for a custom AVCHD I have made. Are .sup files from a DVD compatible with AVCHD or do I have convert them? (I plan to mux them in with tsmuxer and don't need to change the timing of the subtitles at all.)
EDIT: Well tsmuxer won't accept them, so I suppose .sup files are not compatible. How do I convert them?
