I read the primer/FAQ here regarding HDTV basics because I needed to understand signalling differences better. It has helped me but I am confused about one thing with my TV. I tend to watch most of my programming in TW1 on the Tosh but the manual says I should "select Natural size to view a conventional 1080i source in the wide-screen format." The diagram in the manual associated with this suggests there are no bars on the sides. Now, I know when I watch conventional 4:3 programs in natural mode, I get the light gray bars on the right and left sides (and subsequently use TW1 to get rid of the bars). I have tried to find a program where I thought it was being broadcast in HD (the NCAA games, CSI etc) and used my natural mode but I still get the gray bars on the side. In fact, I have not found any program yet where those gray bars disappear in natural mode. I have a Time Warner digital cable STB that acts as my HD receiver for the Tosh but I must be missing something or doing something wrong. Any thoughts?
