High definition DVD, also known as HD-DVD (which actually stands for High Density DVD), is one of two competing high definition storage format - the other being Blu-ray. The need for a new, high capacity storage format, has been primarily brought about by the rapid rise in popularity of HDTV in Japan and the US. HDTV has much higher bandwidth than either NTSC or regular DVD discs, so in order to record programs from HD- DVD higher capacity discs, of at least 30GB, are required. High definition video is also being used increasingly to make Hollywood movies as it offers comparable quality to film at much less cost. Therefore, the studios plan to release future movies on one or both high definition formats. HD-DVD was developed by Toshiba and NEC and has the support of the DVD Forum, along with a number of Hollywood studios. Currently those studios which have announced support for HD-DVD are; Universal Studios, Paramount Studios, Warner Bros., and New Line Cinema. It has a capacity of 15GB for single-sided discs and 30Gb for double-sided. It doesn't need a caddy or cartridge and the cover layer is the same thickness as current DVD discs, 0.6mm. The numerical aperture of the optical pick-up head is also the same as DVD, 0.65mm. Because of its similarities to current DVD, high definition DVD is cheaper to manufacture than Blu-ray, because it doesn't need big changes in the production line set-up. Both HD-DVD and Blu-ray have backward compatibility with existing DVDV discs. That is that current DVDs will play in HD-DVD player, although new high definition DVD won't play in older DVD players. High definition DVD currently supports a number of compression formats, including MPEG-2, VC1 (based on Microsoft's Windows Media 9), and H.264 which is based on MPEG-4 and will be supported by the next version of Apple's QuickTime software, which will be included with Mac OS X Tiger.

How to Connect DIRECTV HD DVR to a DVD RecorderTelevision programs, unfortunately, never air according to our schedules. As people we tend to get very busy and we find ourselves wanting to relax in front of the television because it is relatively cheap, safe and we do not have to go anywhere to see it--just to the comfort of our own living room or television. With the invention of the VCR and now, subsequently, the DVR we can save our much loved television shows and movies directly to the hard drive that is included inside the DirecTV receiver. The bad side to this technology is not being able to take it with us. We are paying to watch the shows which gives us limited ownership to them so now we an add a DVD recorder to the rest of our video equipment so that we can record from the DVR to the DVD recorder.
