Player analytics and pageviews

I see my pages with a player have hundreds of pageviews in Google Analytics but roughly 8-10% of those pageviews are being tralsted into “Plays” (according to google analytics).

Apart from the obvious (users don’t really click “Play”), does anyone have any insights as to what can be happening? Is the Flash player (for those without HTML5) sending “play” events to Google Analytics or is there any other technical consideration?
