I seriously considered doing something like this myself. After exhaustive research i decided it was much to expensive for a one off proposition. If you want to perform a full on calibration with grey scale and gamma in the service menu i suggest you get reading . Alternatively , hire someone to come do it for you. In the end , i bought the disney WOW disc as well as the Spears and Munsil, the disney one is really easy and the results were very good imho. If money is no object you can get a Lumnagen, which will, along with a light meter and its processor can calibrate your projector for you automatically.
