DVD playback over Multi-room by copying to the hard drive of a primary device in a networked multi-room system. A method of manipulating optical energy within a waveguide includes optically coupling at least one annular optical cavity with the waveguide; and selectively controlling an electrical field in the at least one annular optical cavity to modulate optical energy from the waveguide. The dispenser includes plural first nozzles for spraying a first color photo-resist onto the substrate, plural second nozzles for spraying a second color photo-resist onto the substrate, and plural third nozzles for spraying a third color photo-resist onto the substrate.
