Here's the rest of the XBMC string - the displays aren't quite right anymore - the livingroom has been upgraded to a Samsung 46" LED LCD, and the 42" moved to the master bedroom. The master's plasma moved to the guest room (no pics). Yes, I like toys, have no kids (but a very understanding wife), and more money than sense sometimes
Need a beverage? Go to the wet bar just outside the theater and keep watching the show
Or head up to the living room and relax with a smaller screen
Retire to the bedroom and never miss a show
You can even stay on top of the show while making dinner in the kitchen
And when I need to go do some work in the home-office, I still have my trusty old 8-year old 42" Panasonic TH-42PWD5UY plasma (and a bunch of toys)
Every screen you see is driven by the same set of components in the server room / wiring closet. The theater is a special case and has a dedicated touchscreen Pronto remote and digitial audio/surround. For every other room the signal is distributed throughout the house using component video + stereo audio. Each room has a flat-panel on the wall and a Harmony 880 remote - nothing else. I like to think of it as a 'zero footprint' installation. I use a Xantech IR distribution system to keep everything in control and an Extron Matrix50 component video distribution matrix to route all the signals.
XBMC is the icing on the cake!:D
