+// OK, a casual overseer of this file may wonder why we don't use
+// either CreateMovieControl or HIMovieView...
+//
+// CreateMovieControl
+// 1) Need to dispose and create each time a new movie is loaded
+// 2) Not that many real advantages
+// 3) Progressively buggier in higher OSX versions
+// (see main.c of QTCarbonShell sample for details)
+// HIMovieView
+// 1) Crashes on destruction in ALL cases on quite a few systems!
+// (With the only real "alternative" is to simply not
+// dispose of it and let it leak...)
+// 2) Massive refreshing bugs with its movie controller between
+// movies
+//
+// At one point we had a complete implementation for CreateMovieControl
+// and on my (RN) local copy I had one for HIMovieView - but they
+// were simply deemed to be too buggy/unuseful. HIMovieView could
+// have been useful as well because it uses OpenGL contexts instead
+// of GWorlds. Perhaps someday when someone comes out with some
+// ingenious workarounds :).
