You can therefore only use this installer if you have a Wii without hardware modifications because it will force libdi to always use the so-called DVD video mode which is not supported by many modchips. I’m afraid that you’ll have to wait for BootMii if you have a modchip without DVD support and want homebrew to be able to read your DVDs and if you did not install a hacked IOS and DVDX previously.
Please note that this only is a temporary solution that was only released due to the high demand. It will be replaced with a better solution once BootMii is available.
