Just wondering what mode y'all watch movies in. I've read some threads regarding screen burn and there are some who say it's a thing of the past. I've had Pioneer PDP-508XD for just over a year and watch movies in the ZOOM mode, this gets rid of the black bands at the top and bottom of the screen. However I've recently purchased a Panasonic DMP-BD55 and wanted to just leave it in the FULL mode to get the true cinema feeling. So is it safe to watch movies in the FULL mode or will I be left with screen burn, the operating Instructions do warn about this.
