I have noticed during last night's Monday Night Football game as well as last week's MNF game that when the halftime show was on, or where they showed lighter, grainier, upconverted 16 x 9 SD, that you could faintly see the outline of the 4:3 bars, i.e., the areas around where the 4:3 picture would be, looked a shade darker...I am thinking this was ABC's equipment as I haven't ever noticed that when watching a 4:3 show and switching to a 16 x 9 show that there was anything like this. I don't watch a lot of 4:3 TV, basically only on commercials when watching some HD over the air only. Anyone else notice this? I have a TH-PWD5 Panasonic 42".
