IDVREngineHelpers Interface (Windows CE 5.0)
This interface is exposed by both digital video recorder (DVR) source and sink filters. It allows applications to delete recorded files to help manage storage space. An application can call the methods of IDVREngineHelpers on any instance of the DVR engine regardless of the engine's state. It is possible for an application to create a DVR sink filter, never connect it, and use it solely for the purpose of deleting recordings.
