I have combined both MCE 2005 cd's into 1 installation folder and then slipstreamed SP3 into it. Then I replaced the medctroc.in_ and medctroc.dl_ with the original files from the cd and then put this on a dvd. During the setup it asked for napclientprov.mof. If I press cancel it does not install the media center components. Has anyone gotten around this problem?
