These next generation movie formats bring six times the quality of that of regular DVD. How can this be achieved? It all comes down to the media used to store the movie data. HD-DVD and Blu-ray discs are able to store much more data than a regular 4.7GB DVD disc. In fact, the storage capacity of a double sided Blu-ray disc is 50GB and HD-DVD is 30GB – even for the latter, that’s over six times the capacity available from the previous DVD standard! That allows film studios to sell movies at much higher resolutions up to 1920 x 1080, which are progressively scanned, for amazing life-like quality and extreme clarity. If you’ve ever experienced true HD content on a large display, it’s easy to become highly immersed in the scene and it really feels as if you are there in the same environment. In comparison and even when HDTV’s do their best to upscale content, DVD quality feels like looking at inferior piece of junk. Forgetting about the whole DRM and HDCP debacle, it’s awesome technology..
