+/**
+  * PlayerWidget subclasses MVideoWidget from libmeegotouch to add policy awareness to this
+  * widget and also some convenience methods / overrides for our demo.
+  *
+  * MVideoWidget is the control for video playback, but apparently also outputs audio as well.
+  * It has the basic play(), pause(), seek() functions and contains the state of the playback.
+  *
+  * We override play() and pause() so that if demo is running in the policy-aware mode (the default),
+  * an audio resource is acquired for each playback operation.
+  *
+  * \see MVideoWidget
