svpe has released an official version of DVDx for System Menu 3.4. Note that PatchMii and advanced modes are unavailable for this version.

DVDX is a homebrew application that installs a hidden “channel” which can be used by other homebrew applications to access home burned and factory pressed DVD content without the need for a modchip. This does not modify any IOS in any way, making it very safe.

Thanks to http://www.wiibrew.org for the news.
