If you're just publishing to DVD, you'll be fine, even after tossing all that quality out the window.
This all has to do with how the CCDs are made. If they're cut to 4:3 standard shape, then you lose a few pixels when you crop out the top and bottom. Now there are special (Anamorphic) lenses that allow you to shoot wide with a standard CCD cam and not lose quality, but if you're not shooting for the big screen, I wouldn't lose any sleep over it.
The Sony FX1 (for one example) shoots natural widescreen (CCDs are 16:9), so you have to crop out some pixels to shoot standard. Maybe what we need are mallable CCDs that we can reshape as needed! X-D
