Hgeifman,
The plasma burn in problem is not what it used to be but you should still be cautious. I did not watch many programs in 4:3 format. I used the satellite stb format to stretch/zoom etc. When I did watch a program with the side bars I always switched stations during commercials. It is only the black sidebar that you should be concerned about. You could try to find a used DVDO Iscan hd+ as this will zoom to your specifications and you can zoom out the otherwise unremovable black bars on a digital ota transmission (if you use your rooftop for local hd).
Hope this helps.
John
