"With the worldwide launch of the Xbox One, Microsoft is now busier than ever dealing with errors, hardware issues and other queries that need clarifying. Lead for planning on Xbox 360, Xbox One and Kinect Albert Penello recently answered questions regarding a number of topics."
Update To clarify: The Xbox One is constantly buffering five minutes of whatever you're playing. If you want to capture a short, 30 second clip then you can say "Xbox, Record That". The maximum length of a DVR clip is five minutes but you need to snap Game DVR and manually record it. The maximum clip length for the Xbox One's DVR is NOT 30 seconds.
