how is your install in rrconfig under VIDEO&DVD ?
did you select "Video Auto Hide" ?
if yes, what value for the timer you use ?
in riderunner if i use the cmd SHOWCONTROLS and HIDECONTROLS on videoplayer.
hide fits the video to fullscreen. but show don't fits back the video back to the area in skin. the video stays in fullscreen mode but i can see only the cutted area.
my video player plugin is ms directshow.
only when i move the mouse on fullscreen, the video fits back.
