ok, let me explain..After I connected the s-video cable, I was able to see the complete desktop including the Start menu. i wanted to watch a mpeg video using the power dvd and was initally able to see the power dvd window on the tv screen until i loaded the movie into it. after loading the file, when i tried to do a full screen the video screen turned blank. as soon as i exited the full screen everything was ok, but i was not able to see the movie playing in power dvd. I went into the display settings and found two displays there 1 and 2 with 1 as primary and 2 having set as primary option disabled. There was something written drag the icon on top of the other to set the display for same size or something like that. so i draged the icon 2 on top of icon 1 and clicked apply and something went wrong and I lost the mouse control on the laptop monitor and at the same time the tv monitor stopped displaying any windows except the desktop wallpaper. I then rebooted the machine which fixed the laptop monitor issue but the tv output still remains the same. this is all i did.
-thanks
