No, if that screensaver is not live streaming, then it have NOTHING to do with what we are talking here.FYI, what Jason is reporting is similar to what I sent last fall with with AppleTV screen savers flashing. It seemed to have gotten better but still happens once in awhile with them. It seems to usually happen on the ISS flyovers where an edge is mostly black and the earth is starting to hit the light trigger zone.
I think I've seen it playing videos in Infuse and YouTube on it also. I thought it was the channel Home Theater Gurus that it happened. He has a bunch of videos in front of a white board with a black boarder and his head going into the margin was causing it. I've spot checked a few of them and haven't reproduced yet. I'll let you know if I can find a sample.
But the solution we will implement for this issue will fix that too.
