While I've never seen that model, the TV tuners may not be found if we forgot to install the XP motherboard chipset driver package. Hint? Dell.com, the service tag and look at the drivers for this OS.
Help - I have a Dell computer running Windows XPS200; I can open media center & watch tv on my computer; all of a sudden, I now get a message that says: tuner not installed - no tuner hardware detected. I called Dell & downloaded & installed their ATI tvt2 wonder elite-internal analog ntsc tv tuner; but media center doesn't recognize it. What specifically do they mean by tuner hardware? Does that mean the ATI piece that is screwed in the inside of the tower? Is this something I can download from the internet? Thanks for your help.
