I think you should widen your perspective from TV programmes to broadcasting in general, and include especially radio. Why? Here is the answer:
You may listen to programmes of Deutschlandfunk (German public radio), and you will find transcripts of many of their programmes (like interviews, features, etc.) on their website. Also on the website you find a button to listen to the respective programme, so the parallel use of audio and transcript is easy to do.
Here is a current example (of 1st May 2020):
Notes:
- Don't mind the perhaps very special topic. I just picked the first transcript-and-audio page of Deutschlandfunk I came across today.
- Ups... after listening to it the first 5 minutes, I must say: this is a very good programme! Quite interesting perspective on the Judas story. :-)
- On checking the searchability (in Firefox: Ctrl f opens the search window for page content) I see that in the aformentioned transcript there is a problem with Umlaut: Letter ä, ö, ü are rendered with the wrong character, and so if you search for "Täter" (which is there in the audio), you would not find it. But I suppose that this is a glitch in the current transcript and not a recurring mistake in these transcripts.
