From my testing, I have found the judder to be independent of the upscaling. I run my 59Avi DVD player at 1080i and connect it to my 1110HD via HDMI. I have tried the four different pulldown settings on the player (off, on (3:2), auto1 (3:2), and auto2(3:2)) in combination with the three settings on the PDP (off, std (3:2) and adv (3:3)). I have also tried 480i, 480p, 720p, and VGA for crying out loud.
I have come to the conclusion that the root cause of the Pio judder problems is misinterpretation of flags and candences. I attribute this to by observation that the judder effect is (a) not increased / decreased with any particular combo of player / plasma pulldown or upscaling and (b) it is
a function of the material itself. Let me explain.
Secrets of Home Theater (I think it was them...) have reported that the LOTR DVD's are full of flag errors. I have noticed that the judder problem is worse for "live" scenes and virtually zero for digital scenes. Bad judder occurs when Jackson (or his remote director) uses one of those sweeping / rotating landscape shots with a lot of horizontal movement of distant mountains against the sky. The higher the contrast between the mountains and the sky, the more noticeable the judder. It can also be seen in indoor scenes that are live-shot. The effect is really only noticeable in horizontal pans.
For scenes where there is a flyover of a digital scene (e.g., the sweeping shots of Minas Tirith come to mind), the movement is very, very smooth and filmlike except
for the first digital scene at the very start of a track / chapter. The very first scene in the chapter does exhibit some judder, but the very next scene does not. I attribute this to candence errors on the part of either the DVD or the Pio.
In the case of HD material, the judder comes and goes, but I have seen it in both live and digital / CGI material. For example, I PVR'ed Attack of the Clones in 1080i off CBC HD, and the scene were Padme's cruiser is landing in the opening scenes, the judder is phenomenally bad. Later, when Anakin & Obi-Wan are chasing the bounty hunter through the night "streets" of Coruscant, everything is silky smooth (and phenomenal to watch with Pio's vibrant colours).
In other words, the Pio certainly can do very, very smooth, filmlike pulldown (I've seen it do it quite a lot) but it seems to get tripped up on some scenes more so than other displays.
My hope (dream?) is that this can be corrected via a firmware upgrade sometime in the future...
