I want to calibrate my PLV Z1 to maximize the PQ. Source is a Philips DVD963SA outputting PAL progressive. AFAIK there are no PAL calibration dvds available as yet, and I don't want to wait weeks for one to appear! The Video Essentials (NTSC) calibration dvd looks the best for me so far. I've got mainly R2 dvds and a few R1s. Will the calibration help both types of dvd? Anyone else calibrated this setup (Z1 & 963SA)? What results did you get? Thanks.
