It might, but you would have to have the perfect reverse image or you might end up with a strange burn in.
Here is the basic deal with burn in. Its perfectly avoidable by taking several steps
Lower your contrast (white level) below 50%
Keep the brightness (black level) near or below 50% (There are differing opinions on this one)
Stretch everything in the first 300 or so hours of the TV. Your set is more susceptible to Burn early in its life, and as time goes on there is less of a chance.
If you watch a lot of 4:3 and wont stretch buy a LCD, DLP, LCOS or D-ILA.
Its fine to watch things with black bars occasionally. After your initial break in don't worry about watching a 2.35 DVD, just make sure you that you fill the screen most of the time.
There is life with technology that burns. It just takes some minor adjustments to your viewing habits.
