Since getting the Summer 2014 software update, I've noticed a bug with the aspect correction mode setting. I have it set to Panel on a 16:9 display. Overnight, the video changes to Full aspect, but still displays the setting as Panel. Every time I reset it, it switches back to Full a day later. The only way to reset it is to toggle through the aspect settings using the zoom button. I prefer Panel when viewing old SD programs so they don't get stretched horizontally. When set to Full, they are stretched horizontally to fill the screen. Previously, this setting would stick, but now it gets reset overnight.
