I am having a problem getting this TV out of letterbox mode with the DTC-100. I have the DTC-100 set to 4 X 3, however this TV still shows everything in letterbox. There is an enhanced 16 X 9 selection on the Sony that is set to automatic, and will not let me change to manual. The selection is grayed out. When I watch through the s-video port all is fine. It is only on the component input that there is a problem. i hope this makes sense. Any help is appreciated.
