I am seeing visual jitter in the playback of HD iTunes TV content via ATV3. By "jitter", I mean that it looks like there are frame skips and/or discontinuities in the motion. I am quite certain it is not a buffering problem. I have a fast network, it is connected by ethernet (not WiFi), there is plenty of buffered video, and there is never a glitch in the digital audio. TV is the latest, top of the line Panasonic LED, with 24P cinema playback capability.
