It seems that if the video have a human write subtitle, even not in English, youtube-dl will not get the auto-sub, but the auto-translated-sub, which doesn't contain any word-time info, but only the start time and end time.

[dstftw]

1. --write-sub for regular subtitles.
2. You're getting exactly what Youtube provides.

I mean I want to get the auto-sub, the regular subtitles is not what I want.
