I unistalled my power dvd. The Samsung dvd is still listed. Nothing happened when I reboot my computer. First it says hit any key to boot cd'/dvd and then it loads to windows. I now have an icon on my tray next to the time. It is a gray otogon with a red and yellow stip on it. I click on it and nothing happens. I right click and nothing happens. I go to my computer and then click on dvd and you can hear that its trying to do something but nothing happens.
