This may sound like a dumb question, but I recently bought a Samsung HL-T6187S. I have it hooked up to a DirecTV HR20-100 receiver. Whenever I put it on the SD stations, I notice that the black bars on the sides, are not even. The left side measures at 6.25" wide, and the right bar measure at 6" wide. I checked this on different stations, with the same result. Questions are :

1. Does my TV need to be adjusted?

2. Is this a normal feature of the 4:3 view on a 16:9 TV?

Also, when I put it on the Directv Guide screen, It appears that the Info bar at the top, is not level The top right edge, tilts upwards a bit. Most people probably wouldn't notice, it but, being the anal person that I am, i see it every time.
