The subtitles are variable. I depend upon them as I cannot watch TV without them. At the moment I'm trying to watch Apollo 13 but the subtitles are so out of synch that it's unwatchable.
Welcome to our forums and thank you for posting. I'm really sorry that you've been having difficulty with the subtitles for certain content.
Could you please confirm whether you were watching live TV, a recording from live TV, or On Demand via the search function?
