MCE Everywhere
Steve’s a home theater installer and went a little nuts with Media Center, MCE = Media Center Everywhere (via Sean in email):
The TVs don’t use Media Center Extenders to access the MCE interface and content. The s-video output of the video card and the sound output of the sound card of our media server running MCE 2005 goes into a Leviton modulator that outputs the MCE audio and video as a channel, 78 in our case.
