I upgraded my Oppo DVD's players firmware and got hold of Avia yesterday to calibrate my Oppo and Panny AE700. I done the flicker tweak some time ago and have never had to repeat it. VB is almost completely gone since I did it. I don't have any filters so can't do colour tweaks. I set my colour to +6 on the AE700 simply because that looks good to my eyes. I use the Normal picture mode and low lamp level. I set the Oppo to defaults and just calibrated the AE700. It came out a -4 for contrast and -3 for brightness using Avia. Watched The Phantom Menace, looked good but a little dark. Brightly lit scenes were fine but I found myself peering at little on dark scenes to work out what was going on. I then used the simple THX optimiser that comes on many DVD's and it came out at -3 for contrast and +3 for brightness. Watched Attack Of The Clones and it looked great. Best picture I've had out of my AE700 yet. Very vibrant colours, seems to shine off the screen in bright scenes and nice and detailed on dark scenes. The Oppo's upscaling also gives it a really smooth, filmic quality. So it looks to me that the 'free' THX optimiser does a better job than the very expensive Avia.
