I am considering taking the plunge and buying a large screen TV. I'm attracted to Sony's KF-42WE610 rear projection LCD and the Samsung HLN4365W or HLN437W DLP because of their relatively low profile and price, as well as some of the things that I have read about them. The principal use I would make of a larger TV would be to watch DVDs. We live in a rural area and don't have cable. Our DVD player still works great but is a little older and does not have progressive scan. How will DVDs played on my player look on these larger sets? Would buying a large screen be a waste without also upgrading the DVD? I don't really want to replace the DVD player if I don't have to, since it's working great. Appreciate any thoughts, thanks.
