heres a vid of it working form me as alwaysCode:August 12th, 2008 by Erant As you all know, Iíve been working on libdi (or the DVD Access library) for a while now. We had some problems getting it out to release because of the difficulties we encountered while writing the second part of this topic. The DVDX installer instead will install a small, hidden, channel on your Wii that allows you to read DVDs on an unmodified system. It is not an installer for a patched IOS. You may however need one, depending on your system. Usage of this package is fairly simple. Run the installer.dol found in the package, follow the onscreen instructions, and youíre done. Once youíve done that, you can enjoy the splendor of mplayer. That what started out as a simple proof of concept has rapidly turned into a full-featured media player, under the nourishing hands of dhewg. The main aim of the mplayer project was to get DVDVideo going, but it also supports reading video files off the SD card. (Experimental). A patch for Wii64, the N64 emulator for the Wii, will also be available shortly. This patch will allow you to read games off a DVD.
