I have a Dell 8400. Can someone please tell me what the difference is between the Dell Media Experience software and the Windows XP Media Center? I'm fairly new to Dell, and I can't figure it out. I know I have the DME, but I haven't seen the Win XP Media Center on my computer. Also, when I go to DME and click on Radio Stations, nothing plays. The list of songs will play, but not the Radio Stations. Thanks for the help.
