When moving to a bigger plasma or LCD screen, even an SGVA cable doesn't really cut it. I bought an upconverting player with the new Toshiba. It can output 1080i via an HDMI connector and this should be automatically converted to true 1080p on my REGZA model. A DVD cannot have true high-def though. A standard, duel-layer disc can only hold a smidgen over eight gigabytes which is only about a third of what future high definition discs will be capable of storing.
I borrowed Sweet Hereafter (1997) from the library. It's a wonderfully slow-moving Canadian film. It occurs after a horrible school bus accident in which children are killed, so it's definitely not light fare. It shows the effects on a small town. Most of the outside sequences were filmed not far away in British Columbia. Although there's no snow where we live, the mountain ranges are now white just like in the film. Spences Bridge and Merritt, BC looked fine when shown on the three-foot wide screen. If you can get hold of this disc, it's worthy viewing.
