My system has all the TV Tuners and options you could want to enjoy the digital TV in the Media Center.When having the necessity to change operating systems from Vista Home Premium to Vista Business, I lost the Media Center and I really miss the Digital Interenet TV I had.Vista Business doesn't come with the Media Center but my computer still has the hardware.I've attempted to download the Media Center but its not offered in a download. What do I have to do to get it back?

You may have to revert to Home Premium and run your Vista Business image in a virtual machine. In any case, Vista is not a "desirable" option. Have you looked into upgrading to Windows 7?
