I've got a 63" C8000 Plasma and I experienced some ghosting (crosstalk) during the ESPN 3D World Cup match (Germany vs Australia). I noted several observations:
1. Not all things are out of sync. Objects closer to the screen vs objects further away from the screen would vary depending on how I adjust the 3D view parameter (-5 to 5). During the game the best view was -1 or 0 whereas during commercials it would change anywhere between -5 to 5 to eliminate ghosting. Even with the adjustment some objects from the screen would still have ghosting. For example, when the big Gillette blade was spinning around the handle part had ghosting and the blade part didn't. When I adjust the 3D view parameters it would improve the handle part but it would create ghosting on the blade part. It's a bit annoying that this is happening and I'm curious if other folks who have Panasonic sets are experiencing this. I'm suspecting that it may be the TV or from the network.
2. I paused a scene where ghosting occurs and it stays like that, so it isn't due to phosphor lag. I'm suspecting that the sync of the glasses to the PDP refresh rate is slightly out of sync. Btw, I'm using the battery powered glasses and I'm wondering if the rechargeable ones causes this problem, too? It's possible that the glasses have some kind of lag even though the sync signals match.
FYI, I watched mine through Directv channel 106.
I want to get to the bottom of this because It's bothering me.
Also, I'm using a high speed HDMI 1.3 cable to the PIO receiver (VSX920K) and HDMI 1.4 cable to the TV.
