I read TV. I often turn on captioning, especially when it's a British show. And often they mix the soundtrack of movies with so much dynamic range that the loud parts scare the dogs and rattle the walls and when I turn it down, I can't hear the dialogue, so again...captioning to the rescue. And foreign films really need to be viewed with subtitles rather than dubbed!
But for the most part, I really don't want imbedded video and all kinds of crap cluttering up my reading experience!
