 /* ChangeLog added 2002-01-10
+ * 2002-12-24: (Hohoho)
+ *  Added patch from Thomas Jarosch <tomj@simonv.com> which adds support
+ *   for setting the TV norm by movie framerate.
+ *
  * 2002-11-03:
  *  Cleaned up syncing code and renamed setup variables so
  *   they can be accessed from the GUI.
