i have tried to find a solution for this but no luck. i have a 2 year old dell vostro 200 duel core e4500 w/ 2.2 ghz and 2.00gb. running windows xp-medial player 10 and adobe player 10. streaming movie sites allow for full screen play but i cannot get this option to stay. full screen will stay on about a minute and then revert back to the small screen. i have disabled the screen saver and set display times to not interfere w/ movie play. this is really irritating since i am sending this to my hdtv. no one i know has this problem. it is probably just a setting i need to adjust. thanks in advance for any suggestions.
