Not to take this off the subject, but I'm pretty sure that the
projectors don't use the DLP (digital light processing) chips, but are
projectors built by Hughes-JVC.  These projectors use LCDs with a direct
radiating lamp that reflects off the LCD.  The DLP is a very good
technology for
home theaters, but doesn't provide the resolution for a theater size
presentation (limited to about 1024x768 grids at this point).
