You talkin’ about anamorphic widescreen, BMU? If so, every DVD player should have the capability for it, since as I recall anamorphic widescreen is part of the DVD hardware standard. That doesn’t mean, however, that every widescreen movie is anamorphic…
I’m simplifying, but the idea behind anamorphic widescreen is to give optimal picture clarity to owners of widescreen displays (TVs with a 16:9 width-to-height ratio, as opposed to modern 4:3 displays. When HDTV becomes the norm, we’ll all have widescreen displays). The movie is recorded on the disc at a resolution that, to owners of regular TVs, would look “stretched”. To make the image appear normal on a 4:3 TV, every fourth line is removed, eliminating the “stretch”.
Owners of widescreen displays, when viewing a letterboxed movie, have to do a sort of “zoom” to make the image fill their screen. Without those extra lines, the zoomed image can look a bit blocky. With them, everything’s nice and smooth.
But, like I say, I’m oversimplifying. Check out this article for better info.
As far as DVD players go: Hell yeah, they’re worth getting! The picture is nicer, the sound is much much better, you can jump straight to your favorite point without fast-forwarding or rewinding, you can fit over 6 hours of video and sound onto one disc (with DVD-18), you get nifty extras like trailers, deleted scenes, games, commentary tracks…not to mention that they don’t wear out like videotapes. And, you can rent DVDs by mail from Netflix.
No, the movies are not all in letterbox format, but letterbox is generally preferred, and for very good reason. With letterboxing, you get the full width of the theatrical screen; you see the movies exactly as the director intended you to see it. On movies that have been “altered to fit your screen”, some yahoo had to edit a new version by sliding a window across the full width of the display, cutting off significant portions of the action. I can’t stand watching movies in pan-and-scan anymore; I’ve come to notice when the movie’s been edited for the small screen, and I find it distracting.
Go buy one. They’re nifty.
