Message from Erant on Hackmii
As you all know, I’ve 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 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.

MPlayer - dvdlib edition
(c) 2008 Team Twiizers

ABOUT
-----
This is a native MPlayer (Entering MPlayer homepage) Wii port.
The main focus has been DVD-Video playback on modified and unmodified consoles.
Although you can open and view various media files from SD card, this is
largely untested. At this time it can not read files off data DVD's, just
DVD-Video discs.

REQUIREMENTS
------------
This application requires a valid and working DVDX stub install, please refer
to its README for setup instructions.
A DVD-Video disc, either pressed or with the DVD-ROM booktype, might also come
in handy.

INSTALL
-------
Just copy the "mplayer" folder into the "/apps" directory on your sd card and
launch it via the HBC (The Homebrew Channel).

RUN
---
When launching this application you will be presented by a basic on screen
menu. All options should be self-explanatory, here're some hints:
- High bitrate video streams may lead to dropped frames. This really depends on
the used DVD-Video. Some fullscreen movies seem to have the same issue.
- Hiding the menu and disabling subtitles improves the performace a little.
- Playing DVD's with libdvdnav is buggy and decreases performace (read: way
more dropped frames)
- Choosing a DTS audio track results in noise and breaks things.
- Choosing non-playable files from SD makes it crash & burn.

CONTROLS
--------
You can use a wiimote or a gamecube pad to interact:

A - Pause
B - OSD
1/X - Toggle on screen menu
RIGHT - Seek 10s forward
LEFT - Seek 10s backward
UP - Seek 60s forward
DOWN - Seek 60s backward
+/R - Seek to the next chapter
-/L - Seek to the previous chapter
HOME/Z - Quit

When watching DVD's using libdvdnav:
2/Y - Modifier key for libdvdnav

Hold this key and use RIGHT / LEFT / UP / DOWN / A / B / 1/X to navigate.

CREDITS

HOW TO BUILD
------------

3 subversion repositories are required to build this port, the revisions used
for this binary are:

libdvdread r1120
libdvdnav r1120
mplayer r27458

- get the repositories via:
- svn co svn://svn.mplayerhq.hu/dvdnav/trunk/libdvdread libdvdread-trunk

- svn co svn://svn.mplayerhq.hu/mplayer/trunk mplayer-trunk
- apply the patches
- edit libdvdread's and libdvdnav's config.mak and adjust SRC_PATH and
SRC_PATH_BARE
- build libdvdread with `make`, then `make install`
- build libdvdnav with `make`, then `make install`
- build mplayer with `make`, test your build using `make upload`

Enjoy,

When I click on the downloads all I get is 403 forbidden.

That's odd I'm getting it too now dont know what going on at hackmii so i'll upload them to rapidshare or something but I don't have patchmii though.Ill have those links in a few secs.

It seems to be fixed now but here are rapidshare links:

Video I made on how to install and shows it working.

@cheez
1.What I have found is that for burnt screener or pirates you can simply go to play dvd instead of the libnav since libnav is a little more buggy.But if your using an original or burnt with menu you can do normal play and it will try to play the main video and skip the menu but it may not always work Or you can use libnav to acces the dvd with menus using 2 and direction to navigate.
2.Why do need to put the di folder on from of sd card I didnt i believe you only need the installer.dol in the di folder in root/apps/*****/ with installer.dol renamed to boot.dol that is the only di file you need the rest are source code.

Just a though, since this has been released...

Do you think this could lead to playing backups without a modchip?

It might be possible but i think bushing and erant put some protection from that so it would be harder for someone to change it into a backup loader.But i still think we will get one sooner or later
