If I let the 1910 convert the component signal from the STB it will not give me a full 1920x1080 resolution, there will be small black bars (1 cm/less than half an inch) on the left and right side of the picture from top to bottom. It is like if the AVR only outputs 1800x1080 pixels of something. If I feed this component signal directly to the TV, there are no small black bars so they are not present in the source signal.
if it is ONLY happening with the cable box, the issue is with the SOURCE as most SD cable signals have "junk" around the edges because these were meant to be cropped out by overscan built into most TV's.
the reason you don't see it with direct connection to your plasma is that the "1:1 pixel mapping" or "HD Size 2" setting on the Panny plasma is ONLY an option with a 1080i/p input (e.g. it's a 1920x1080 display, so it's impossible to have 1:1 pixel mapping with anything but a 1920x1080 signal). So when you plug directly into the display, the plasma recognizes a SD cable signal and locks into "Size 1" or 3% overscan mode.
When you feed the signal to the AVR first, it takes the entire SD signal (including the junk on the edges) and upscales to 1920x1080 -- when this is displayed pixel-for-pixel on the display (because the plasma sees 1080p input so it can do 0% overscan) you see the junk on the edges.
The solution is simply to turn OFF the 1:1 pixel mapping (i.e. select "HD Size 1") for your cable box input.... or just deal with the black bars on the edges and enjoy your new plasma
