I'm programming metro UI app to play movie using player framework version 1.2.0

Everything was fine until player goes into full screen mode.

first, screen saver is not disabled. I hoped screen saver would be disabled in full screen mode, but it enabled and player stopped.

Second, mouse cursor is keep showing in full screen mode.

Third, once I chaged volume slide bar, it keep showing when video controls shows.

Plain video tag player works as I expect. It disables screen saver and hide mouse cursor in full screen mode playing, and volume slide is hidden by timeout.

Is there any workaround for these?
