I have found that watching German media videos with subtitles has helped my aural comprehension (I am not a native speaker of German). Therefore, I am particularly interested in locating subtitled German media videos available for free online.
Bayerisches Fernsehen (BR) offers many videos of previously-aired programs through its Mediathek site.
Some of these videos have the tag UT, meaning that subtitles (Untertitel) are available for them.
Here’s an example of one such UT-tagged video: http://www.br.de/mediathek/video/sendungen/nachrichten/sendung-vom-26122015_x-100.html
(I reached the video above through this page, where it is clearly marked UT [it's the entry titled "Rundschau 16.45 Uhr"]:
this page, however, is ephemeral, so chances are that it won't look the same in a few hours.)
When I watch such UT-tagged videos online (either using a desktop computer or a tablet), I see no subtitles at all1, nor any way to enable such subtitles through the player’s interface.
Is there some other way to access the subtitles for the UT-tagged shows in BR’s Mediathek?
BTW, although I’ve focused on BR’s Mediathek, I have found similar situations in most German media’s Mediathek websites (WDR’s, NDR’s, etc., with the sole exception of ARD’s). Basically, all these Mediathek sites have videos tagged with UT, but I can’t get any subtitles when I watch any of them. I'm hoping that the answer that works for BR’s Mediathek videos may also work for the rest.
As I noted, ARD’s Mediathek is the only exception I know of; its UT-tagged videos reliably include a UT-toggle in their players, and the subtitles do appear on screen when enabled, as one would expect.
1 The only subtitle-related indication I have found for the BR videos is the label [UT Seite 150] that is shown briefly on the screen towards the beginning of the playback. I understand (from the comments below) that this refers to a Teletext page, and is therefore not applicable to the videos available through BR's Mediathek.
