Do any members have an idea why there are black bars at the top and bottom of the screen on Military History? If some of the material is 4:3 aspect ratio there should be bars on the sides, not the top and bottom. However, the bars are always there even on infomercials. I have not seen horizontal black bars since I was watching 16:9 material on an old 4:3 CRT. I am not sure if the picture is stretched or not but it certainly is lower resolution than the other SD feeds.
