My first PJ and I love it. I have it going through a Lumagen DVI scaler but have not tweaked it at all. No need so far. I have found a suitABLE PRESET FOR THE FILMS i HAVE WATCHED. hAVE NOT NOTICED aUTO iRIS YET. aM NERVOUS ABOUT STARTING TO TWEAK, BECAUSE THEN YOU LOOK CLOSER AT THE PICTURE INSTEAD OF THE MOVIE AND i DO NOT WANT TO START NOTIcing faults I do not see just now. Apologies for the caps lock there. Happy to answer any questions but to any newbies out there, please put some peoples posts on PJs in perspective, they have had a few PJs and are looking quite rightly at the fine details, looking for improvements on other models and we need that to get the best out of our pJs. but do not let it put you off. The Sanyo anyway, out of the box is a very filmic image and I am now "At the Pictures" when I enter my garage. Also many thanks to Joe Fernand at the media factory for helping with the instal. I literally could not have done it without him. You will see him on the forums and I highly recommend using him.
