I've been struggling with subtitles for a while and would now like to get them working.
Win 10 running 4.4.0.4 beta (will be updating to 4.4.0.6
Subtitles set to preferred language: English and Mode: Smart
I thought my problem was mp4s and mkvs where the Audio language was Und but I used mp4box to correct one of the mp4s and Smart subs are still not working. The Revenant (2015) is the movie and there is intermittent non-English dialogue; however, the subtitles play for all dialogue or none, depending on how I set CC once the movie starts.
What am I missing that's prohibiting Smart subtitles from working correctly?
