i'm hopeing someone can explain the following. I have a 4:3 screen. when watching movies that are not a full 16x9 ie 1.85 and 2.35 aspect ratios there are these greyish black bars that I see which appear to fill out the rest of the 16x9 portion that is not used. My qestion is why are they grey and not black. This occurs with both WINDVD 4.0 and POWERDVD 4.0. I hope this makes sense. Essentially it just looks weird. I have these grey bar that fill in the 16x9 viewing surface and the rest of my 4:3 screen is a solid black. Why are the bars grey and not black. Can anyone explain this?
