[quote name='gkrykewy']True, but what most people mean when they say 'anamorphic' in this context is that the TV will tell them it's getting a true widescreen picture (720x480 in this case), and they don't have to use any of the TV's stretch settings.
The Wii, when set to widescreen, outputs at 640x480 using rectangular pixels rather than 'true' widescreen (720x480 square pixels).
My point was that there's no reason for this thread to have turned in a direction that people are messing with service menus. Every single person who has a Wii has to use their TV's widescreen scaling (be it FULL, or THEATERWIDE, or whatever) to actually see the correct widescreen picture - unlike progressive scan DVD players, the Wii does not send a widescreen flag signal that will 'force' a widescreen display.
To summarize: EVERYONE has to display their Wii in 'FULL' mode (or equivalent)[/quote]
Exactly. If you set the Wii to Widescreen and let the TV sit with it in a 4:3 box, everything should look very scrunched. Whereas if you "fill" it, it should be just fine, assuming your Fill is an actual stretch-to-fit and not a combination of zooming and other warpings of the image.
I dont' have to adjust those setting on my TV, but I'm guessing it's just detecting it on its own. If I run it through my HD tuner, I have to set it to "fill."
