I tried other conversion beside TO DVD and TO BLURAY, it seems that it is able to merge the subtitle with the video. |
When you convert a video with subtitles to formats other than DVD or Blu-ray, subtitles get saved as a subpicture in the created file which means they cannot be switched off during playback.
However, when you convert to DVD, subtitles are saved as a separate subtitle track embedded into the movie structure. So there actually must be subtitles in the DVD you have built, you just need to switch them on during playback in a player.
