You can use the DisplayRequest class to indicate that you are busy playing back something that requires the display to stay active and un-dimmed. A good how-to article with sample code is available here. Don’t use it frivolously, it is quite detrimental to power consumption. Good odds that the Store will reject your app if you use it for no obvious benefit to the user.
