DVRTrait defines the trait interface for media that can be played while in the process of being recorded, as if with a digital video recorder (DVR). It can also be used as the base class foor a specific DVRTrait class.

Use the MediaElement.hasTrait(MediaTraitType.DVR) method to query whether a media element has this trait. If hasTrait(MediaTraitType.DVR) returns true, use the MediaElement.getTrait(MediaTraitType.DVR) method to get an object of this type.
