Last night my 10-250 started behaving oddly. I didn't change anything in my settings menus. When I've completed watching any 1080i source and return to any menu, the menus are full screen, as they have always been. However, when I then select a 480i source, the picture is resized to 16:9 instead of 4:3 as it's aways been. If I use the up-arrow to switch to 480i, the picture correctly reverts to 4:3, but then all subsequents menus are at 4:3 until I view another 1080i source. This is a mild annoyance, but an annoyance nevertheless. It seems to me I've encountered this before, but I don't remember what the fix was. Anybody?
