I watch the same soccer channel (including the ESPN broadcasts) and I noticed the retention for the first time last weekened when I inadvertently paused the TV on a commercial with a white background. I hadn't really noticed it on my previous Panasonic 42" plasma (branded as HP) which I owned for six years, but I never went out of my way to look for it. After the commercial I checked the scroller and the scoreboard and upper right logo were firmly seated. To be fair, this happened that night after watching the games in the morning and nothing else during the day. Actually, I watched a movie on VUDU, but the logo and scoreboard were located in the black bar area of the movie and didn't see any action to help erase the retention. For kicks, I ran the scroller bar three times and the retention vanished.
I will resume my normal viewing habits (as I did this morning for the games) and simply enjoy the TV as I did with the previous plasma. Incidentally, I broke in the TV with 200 hours of consecutive HBO two to three months ago. I hope to get it calibrated after I pull the trigger on a new pre pro next year.
It's an amazing TV, but then I thought the 42" was amazing (it actually did a better job with cable broadcasts, but that might have been the byproduct of its smaller size)
