After reading many posts...thanks all for the info...have taken plunge and took delivery of shiny new PD30. Now I want to fine tune..so First off, how do you get into the service menu ? What is a good way to test the picture. I have used a THX test sequence from Pirates of the Carribbean, and the factory settings looked a mile out!! I have heard of a test thingy called AVIA or something?? I have Sky digital and an 'Andrew Boss' Prog Scan DVD (bet nobody heard of that one!!), connected with 'Monster' leads. Sky looks great most of the time, but colours maybe a little strong and some green holo effect on some pictures. DVD is fantastic. Any help would be great. I know picture quality is a subjective issue, but I want to know I am getting the best picture that the set can offer. Thanks.
