    Blu-ray and HD DVD, there is still everything to the consumer to win. Millions of euros in marketing stabbed. Both argue that their system is best and it is a pointless device from the competition to buy there is just no disc for it. The format war is long time away from the ordinary consumer play, but is visible since the end of 2006. Most consumers are satisfied with their current DVD player or DVD recorder. In addition, the interests of the companies behind Blu-ray and HD DVD so large that neither of the camps will soon win the battle. i hope that the war will not too long last. Because that will cost tons of money.who is going to pay?

    • Blu-ray has high storage capacity
    • The DVD Forum has approved HD-DVD but not approved Blu-ray.
    • Toshiba also looking positively for HD-DVD standard
    • HD-DVD is less expensive than Blu-ray
    • Blu-ray discs has limitation of the device user friendly where because HD-DVDs could be produced on pre-existing equipment

    entry model (HD-E1) the image in a maximum resolution of 1080i (HD Ready) and can output the new audio standards (Dolby Digital Plus, Dolby TrueHD and DTS-HD Master Audio) only data from the downsampled optical output display.

    The flagship of Toshiba (HD-XE1) may make against the picture in Full HD (1080p) and output through the HDMI 1.3 connection full Dolby Digital Plus, Dolby TrueHD and DTS-HD signals to an HDMI 1.3 amp.
