Sorry that those didn't work for you. I actually got those codes from the files section here. Work great for me in conjunction with the IR receiver I'm using which came with a WMC remote. Just purchased the remote for the IR receiver which under Windows 7 64-bit uses the standard, "Microsoft eHome Infrared Transceiver" device driver. Prior to having those codes I actually used EventGhost to emulate the "Home" and "End" keystrokes, so that's always an option for you. EventGhost is a great program to have running on your HTPC regardless.
