+This class is an extended version of CMMFDataPath. CMMFDataPath is extended to implement the loop play 
+functionality in the controller. This class overrides some of the virual functions of CMMFDataPath in order to
+implement the loop play functionality. All the controller plugins that require loop play functionality should
+use CMMFDataPath2 in place of CMMFDataPath.
