Why would you want timeupdate to fire more often than once per frame? If you tie progress bar animation to timeupdate, the position will update in larger steps depending on the framerate of the video. i.e., a 10 second clip at 1fps will animate in 10 large steps. If your video subsystem returns a wall clock or some continuously increasing time source, the 250ms update will at least give you a smoother animating progress bar. i.e., a 10 second clip at 1fps will animate in 40 smaller steps.
