how do you get back to the media that is playing from the menu

Is there a button that will allow you to go back to the movie or tv show you are currently watching. For example I am watching a tv show and want to go back to the episode list in the library. As is now the only way that I can find to go back to the episode I am currently watching is to hit back all the way out to the main screen. This works and if it the only way it can be done I can live with it but it would be nice if there was just a button that could be mapped to me remote or something. I hope its something simple

thanks in advance
