Grab your SD cards, and boot up the nintendo! Its about time! Finally Bushing and co. has released libdi (or the DVD Access library) enabling unmodified Wii's to read DVD-R's (Movies)
Note, this is not a back up loader
Below is everything you would ever want to know about this releases, so if you are in need of help, make sure you have read everything before asking questions ;)

HackMii Wrote:As you all know, I’ve been working on libdi (or the DVD Access library) for a while now. Wee had some problems getting it out to release because of the difficulties wee 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 you’re done.
Once you’ve 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.
If you have a modchip, you also need patchmii, in addition to the DVDX stub installer.

Erant Wrote:The myth of you being able to ‘burn out’ a DVD laser is pretty much what it says on the tin, a myth. This drive was designed specifically for two things. reading Wii games, and reading DVD-Videos. There are special commands in the drive for doing so. (Wee use these commands to read these discs without a modchip). So, these drives were designed with reading DVD-Videos in mind. (And even if they wern’t, you’re running the entire drive in spec. I’ve been told these myths came about when people were pot-tuning their PS2s, running them out of spec. Running any piece of hardware beyond the limits that were set for it will break it in the long run)
“Wasn’t there talk about how only some modchips needed a patched IOS? Do all modchips really need a patched IOS?”
That’s a ‘no’ to the second question. Unfortunatly, detecting these modchips isn’t an easy job. Wee’ll probably incorporate an auto-detect option into the DVDX installer at some point, but wee were already kinda late, so wee left it like this for now. (It’s also a small percentage of all modchips, think around 5-10%)

To build libdi, you need the Git branch of libogc that wee maintain. Fetch the repository from git://hackmii.com/home/ogcgit/libogc and run make and make install. If you’re under Windows, you can use msysgit.
To everone having problems: remember, this is nowhere near a final release and some troubles are expected.
Regarding protected DVDs: mplayer needs a few seconds (sometimes minutes) to crack the CSS keys for protected titles. Give it some time and see if it starts working. Wee’ll try to optimize this in the future, especially if wee figure out the CSS commands for the drive.
Regarding PAL: quite a few of the people who made this are on PAL. Wee do care about PAL, it’s just that I think it turns out that at least two of us PALers are on 480p anyway, and sometimes wee forget to extensively test the normal PAL modes.
Server’s being glitchly lately. If the links don’t work, please try again in a few minutes or an hour or two.
Both the DVDX channel-stub and PatchMii are only used by homebrew and have no effect on the normal Wii software. They are also not affected by firmware updates (although they could presumably be rendered useless if Nintendo wanted, but they won’t conflict with the updates themselves).
You can uninstall DVDX from the DVDX installer. If you have it installed, an Uninstall option will pop up next time you run it.
If you pick the wrong installation type (normal with incompatible modchip, or patchmii with no modchip) then DVD playback just won’t work - no harm done. You can reinstall with the right type to fix it.

impressive work - good to see some stuff coming out of the Wiibrew scene.
So... Mplayer...... for DVDs?? Mplayer should be able to play many DVD Formats~

Mplayer for Wii up untill now couldn't play DVD's. The files that are flashed are required, and it will only work with MPlayer. This is still in the beta stages of development, more updates will some. Plus this will keep in the movement towards a back up loader.
Thread updated more lots more info :)

this is great man i just wish i could get it going.i can't seem to get my cards to format using the card reader on my laptop.it will do it with my 16 mb card but that's not big enough to hold anything and i also have two 2 gb ones that i just can't seem to get to work.nice though i can see backups coming closer now.

Your 16mb card would be enough to install this and run MPlayer. but yeah that's odd that your labtop won't reformat your card, does you Wii read your 2gb SD card? You might not even need to reformat it unless you have it formated to some weird format.
