I had been watching all channels on my TW40X8 using the 6000s component output and decided to try using s-video for the non HD channels. What I end up getting in standard mode is a 4:3 box surrounded by black borders on all sides for all local digital channels in standard mode. Is this correct for a 16:9 set? I want to use TW1 mode on these channels but I still end up with top and bottom black bars unless I use zoom mode on the 6000. That lowers the PQ significantly. I know the black side bars are part of the broadcast but shouldn't standard in SD mode fill the screen top to bottom like standard in HD mode for local 4:3 ? Why the top and bottom black bars? I checked all the settings and came up with nothing. Any help would be greatly appreciated.
