I have that same TV. Sony Bravia BX31. It makes a nice double ding sound when you open it, right? Anyway, the thing is that the TV only supports .mpg video files. MPG is such an old and useless filetype that nobody cares to make those files anymore. 🤮 The other normal video types (mp4, mkv, avi...) will NOT work. Ayzosh gelete. My solution was to use the SuperMax decoder to play my movies. If you desperately need to watch a video on your TV, use a converter on a computer to change your videos to .mpg format. This will take so long tho.
