I bought a Sony 42" LCD that I am very happy with along with a Sony upconverting DVD player. I am not sure what model. I am trying to track it down from Iraq. I will get it soon. My question is what does upconverting do and are there really only two models that do it, or just two models at Best Buy that do it? You can fill in the blanks. I will be more educated for my next purchase. I am open to replacement or whatever it takes to get the most out of my TV. I am going to make my purchases in November when I come home next. Thanks for the help,
