For example, to display subtitles with Chinese on top and English at the bottom:

1. Open a YouTube video page, and turn on YouTube's native subtitles.
2. Open the Dualsub popup page, and switch to the Native Mode tab.
3. On the row 1, the Subtitle File menu, select Chinese.
4. On the row 2, the Subtitle File menu, select English.

You can select to use human-translated subtitles, or machine-translated subtitles.
