Bob thanks for checking this out. So it is safe to assume that this perception of jitter is normal for a 1080i signal on any display that displays 1080i at 1080i. I just wanted to be sure that it is not a defect in the 59 or my 65813. Your explanation makes good sense and it would be nice if another 59 avi owner could verify this same jitter on their display viewing a 1080 HDMI signal from the 59avi into their display viewing it at a 1080i display rate. Maybe someone else will chime in.
I'm using HDMI to connect my 59Avi to a Pio Elite 1110HD plasma. Pio engineered both HDMI systems, so this *should* be as good-as-it-gets in terms of compatibility...
With 3:2 pulldown, a wee bit of judder (I think jitter is an audio thing) will still be present because 24 frames per second of film doesn't *quite* match up with 60Hz.
Just to make it even more confusing, several of the recent Pio plasmas (4340 / 4345 / 910 / 920 / 5040 / 5045 / 1110 / 1120) can do a 3:3 pulldown (called by their marketing folks "advanced pureCinema") which ups the display's refresh rate to 72 Hz, which is an even multiple of 24 (i.e., 24 x 3 = 72). Hence the 24 film frames can be triplicated and lined up with the 72 video frames.
I have gone absolutely nuts trying different combos of ON / OFF / AUTO1 / AUTO2 on the 59Avi with ON / STD / ADV on the display (STD = 3:2 pulldown) with 480i, 480p, 720p and 1080i signals over HDMI. I have *not* been able to find a combo that works best with all material. FWIW, I'm currently using AUTO1 on the 59Avi with ADV on the display, upconverted to 1080i.
As an aside, the 59Avi also addresses audio jitter if you connect it to an iLink Pio receiver such as the 55Txi or 59Txi (I'm using the former). When you use the iLink, the decoding clock on the 59Avi is locked to the receiver clock using a system called PQLS (Pioneer Quartz Locking System). When I fire up a CD or DVD-A, the 59Avi display momentarily flashes "PQLS" to alert (advertise?) the lock is in place.
One other point. If you put a DVD-A in the 59Avi with HDMI activated, it won't play high bitrate audio (> 96Khz) over iLink due to HDCP issues. Even though I'm using HDMI for video only, I have to disable the HDMI out in order to get the 59Avi to play. This is not an issue for CD, DVD video, SACD, or DVD-A in low bitrate (e.g., DD or DTS) mode. A minor nuisance since I have exactly 1 DVD-A title...
