OK, following the Ticker thread, I went back to store and asked why the Toshiba looked straighter than the Hitachi in strecth mode. He says Toshiba has a better stretch than Hitachi and Mits. He also informed me the Mits would be the same as Hitachi, but they dont sell Mits there.
I guess my question is; Should I be concerned with the stretch modes in different TV's?
Not really. There has to be some type of distortion to fit a 4:3 on a 16:9.
