OK, I just checked my TV. Even though I don't have any working HDMI sources- when I switch the TV to the HDMI input, it allows me to run through the various modes. When switching to "normal", I get a 4:3 blue square matted on the sides. With every other setting, the blue fills the screen.
However, it's possible that this wouldn't work if it was getting a signal. When I try to go through the modes on my component inputs, they all work with the DVD. However, with the DISH 622, "Panoramic" is disabled (can't stretch a source that's already 16:9, I guess), and "Zoom" does nothing.
But again, "Normal" and "Wide" my TV are not settings intended to distort the picture. They simple tell the TV what kind of source material it is receiving. They SHOULD be labeled 4:3 and 16:9, but remember, the CE industry insists on calling 4:3 DVDs "fullscreen", when they are actually the opposite.
Perhaps your TV has the settings in a different place. Maybe you have one button that's just for distorting the picture, and another for setting the aspect ratio. Or perhaps you have to go into a menu, which would be a pain.
I also just realized that DISH receivers label THEIR standard widescreen mode as "normal". Maybe that's what confused you. Yes, when watching HDTV, I leave this set to "normal". However, there are still uses for the other settings. (Except partial zoom)
I have 4:3 monitors in other rooms all fed off the 622s S-Video output. When watching SD programs on these monitors, switching to "stretch" actually makes the programming appear normal. (Though it becomes distorted on the main widescreen.)
And again, hitting "Zoom" on letterboxed 4:3... say TCM... eliminates the side bars, though you will see compression artifacts more.
In any case if you feed the stretched Cartoon Network into your widescreen and tell the TV that it's 4:3, it should appear normal.
I know, there's so many settings and confusing/conflicting labels. I tell my wife "press these two buttons until it looks normal."
