Working on a video player project with osmf and flex i had some strange problems. When going in fullscreen mode the screen it was black or more exactly the video it was not been sown. After one hour of testing and debugging i found the problem, the problem was that i compiled the video player with 10.3 flash player version and this works with hardware accelerated and if there is no video driver or the driver is out of date the video will not be shown only when the hardware acceleration is disabled or you update your video drivers. The solution for this is to compile with older version 10.2 or below witch is not working with video acceleration.
