Using Family Settings to control access to content
If you use Family Settings to control the content that can be watched through Xbox Live on your console, the GameTrailers app will follow these settings.
For example, if you block explicit content from being watched on your console, those items will be marked with a "restricted video" icon in the GameTrailers app. To play a locked item, an adult must enter the Family Settings pass code.
