I have a large video that I want to start playing at exactly 3:00pm
​Unlike a DVD player that starts playing as soon as you push the button, a media player will have to download the file from the internet into its memory first. Depending on the size, this could take some time. If the video has already been loaded into the player, Some players like the IAdea and BrightSign will play the video within a few minutes without having to download it again.
