I will have to spring for an HD system ....eventually. Count me amongst the card carrying ignorant masses when it comes to the subject, but in my research on a similar subject, I read that depending on the model/mfgr there are three ways that 4:3 SD formatted video is handled on a 16:9 screen, One is stretching, without respect to X/Y ratios. YUK! I've seen it and No thank you! As pepper said, why would anyone spend that kind of money for such a poor quality viewing experience. The second was cropping and zooming. X/Y ratios are maintained but you dont get the whole picture. The third is some compromising combination of the two. I haven't looked hard, but the "sales specs" for given hd screens dont even mention how they handle SD, or if it's user configurable based on the info above. When I break down and have to heave out the cash for one of these behemoths, I intend to know, since SD is going to be around in my world for quite some time to come.
