The iPad and other tablet devices are a perfect setting for video playback and it would be great to get some clear guidance. Often videos are sourced from YouTube and it has to be a common requirement to want to show those full screen.
Everyone would be helped if someone could set out a simple app framework to replicate it...and $10 via paypal for a couple of beers for the first who does! !(just the video player, with pinch full screen, element from the example).
