The ltmmSelectionModifier constants define the settings for the SelectionModifier properties for the start and stop selection points. You can use them to specify whether the selection should be exact or on a key frame.
Note that only the MPEG2 formats currently support a selection modifier. With any other source files, ltmmSelectionModifier_None is assumed.
