Some videos on Discovery Streaming have closed captioning (subtitles) and you can download these videos to watch offline. When you do this you can also download the subtitles.
First find a movie that you want to play that has closed captioning available.
You'll want to open the Download menu in the menu bar. Then download the Closed Captioning file. When you download the Video it will open another page in Chrome.
When you get to the new page with the video Right click the video and select Save video as... and you'll want to open up a file explorer window and go to your Downloads (or wherever you saved the CC file).
Copy the file name (but not the extension, as shown below).
And paste it into the name filed of the save window. Click Save.
