Technology always is progressing. HD-DVD won't be the last. Ultra Definition television is already being devoloped. A very early prototype was shown last year. Then again since we had HDTV demonstrations in 1981 but didn't get it till 1998 I suspect we won't get UDTV until around 2020. Todays DVD format has resolution of 720 x 480 quite a bit higher then laserdiscs 640 x 420 and vastly better then VHSs 320 x 240 but it doesn't compare to HDTV. HDTVs uses resolutions of 1080i and 720p. All HDTV broadcasts can look around twice as good as even a very good looking progressive anamorphic DVD. This presents a problem for the industry. As more and more people buy digital televisions they are going to notice that there television shows look better then there bought movies and are probably going to reduce buying movies. A High Definition video format already excists. D-VHS. D-VHS look on the outside the same as old VHS tapes but have resolution superior to HDTV broadcasts and about three times as good as DVD. D-VHS also have quite superior audio. Still D-VHS is a tape and has many tape disadvantages. Rewinding, big size, no extras, and degration over time because of this I have decided not to buy D-VHS. However I have seen D-VHS and let me tell you its not a bit better its way better then even the very best DVD on the very best television. It blows everything away. D-VHS are encoded in 1080i format. Resolution of 1920 x 540. HD-DVD uses resolution of 1920 x 1080. I can only imagine how good they will look. Only the most advanced and expensive televisions we look that good but even on a low end digital television the differences between it and SD-DVD will be ovious. Also HD-DVD is able to be made on traditional DVD assembly lines (its biggest advantage over its rival Blu-Ray) so they can be made and sold for a similar price as the SD-DVDs we buy.
