I have my 811 hooked up to a 4:3 analog set(Sharp 32C540) via S-video, and on some channels I'm getting black bars on top AND bottom(image centered on screen with black border all the way around). It's happening on digital OTA channels(ABC, CBS, NBC, and an independent network from Milwaukee, channel 18). Is there any way to fix this? Is it how these networks are broadcasting the signal? It is not happening on any of the sat. channels, or the analog channels. What is the difference between 4:3(#1) and 4:3(#2) in 811's aspect ratio menu? Which setting should I use? Thanks.
