OK. I got everything installed and most of the software up and running. Everything looks and works great so far. Thanks to Assassin and his guides!
One "hardware" question. I'm trying to do all my configuring on a monitor rather than using the connected projector. However, I've noticed that if the HDMI cable is connected to the PC, the video automatically switches to the Projector and the LCD monitor just shows the wallpaper. Is there any way to toggle the monitors? I've tried Windows-P but that doesn't seem to do anything.
Software-wise, I'm up to the point where I am setting up Windows Media Center and trying to install the Netflix plugin. I get to the 55% installation and it fails, as reported in Guide #4... however, no matter what I do, Netflix doesn't appear in WMC. I've tried reinstalling, rebooting, installing Silverlight separately, and nothing seems to work.
