I was able to get Windows XP activated/validated somehow. I used the second XP disc that I had lying around and when I entered the Product Key on the COA label on the back of the tower, it said that the key was unauthorized. So I wanted to see if the TV tuner would work with XP before I tried buying a copy of it. This required me to reboot the computer and after the reboot, I tried to activate Windows once more just for the heck of it. I clicked on "Activate Windows," and it said "Checking internet connnectivity." Now, usually the screen that prompts you to enter the Product Key comes up, but another screen came up that said, "Your Windows has been activated."
Now that I have apparently activated XP, does anyone know of a good free
TV tuner software program? I've been using either HP MediaSmart (came with my laptop) or Windows Media Center (also came with my laptop) but neither will work with XP.
