I need to control a Hitachi CPX-990 Video Projector with an IR emitter. The only video projector codes in the Circa software are for Sanyo CXHS. Unfortunately this is "one of those jobs", and the projectors are already installed (by others) recessed into a high ceiling. This makes experimentation very inconvenient! Can anyone tell me if the Sanyo codes are common to any other projectors, OR are codes available anywhere for the Hitachi?
