I am working on a WP app and using media player from MS Player framework. I want to customize the progress bar comes before playing video. I generated template xaml for it, but there is no such progress bar.
There is one for advertisement container, but this is for something else because if I removed it, there is no effect still a progreesbar shown with PhoneAccentBrush.
