Status bar not hidden

[buraq01]

I use BS Player on Jelly bean with Tablet UI (i.e. there is no bar at the top, it looks exactly like the ICS status bar). When I play a video, it does not hide the status bar, it just dims the buttons into dots. But the bar still takes up some space. This did not happen in Phablet UI (with the bar at the top for notifications and stuff). Is there a way to hide the bar instead of dimming it?

Thanks in advance.
