the QT GUI Components you get from QTFactory (not sure if you can
instantiate them yourself directly) take care of the tasking themselves. If
you decide say to play an audio file on your own without using for example a
hidden GUI component, then you have to task that movie regularly (either add
it to the Taskable facility/service of QTJava, or call the respective
tasking method of that movie class regularly in a loop [to avoid freezing
all else when using Sun JVM on Windows, add Thread.sleep(0) in your loop])
