from Nintendo-Scene
Team Symbiote (the makers of Wii-Boss) have released a DVD player Application for Wii.

Instructions:

Burn with clone CD, Boot in modded wii with homebrew based
mod programmed with YOASM 1.8 (I used a wii-boss).

When menu comes up then the hit “z” to unmount, change disc to DVD movie and hit “start” to play.

Keep in mind that you’ll want to have a modchip that supports Dual Layer DVDs so those of you with homebrew chips will want to use the recently released YAOSM 1.8 firmware.
