WiiMC 1.0.9 released by Tantric and rodries

WiiMC (Wii Media Centre) is an open source media player for the Nintendo Wii. The GUI is powered by libwiigui.

Attractive libwiigui-based interface, designed with the Wii in mind
Most essential difference from MPlayer CE and the like: completely GUI based, fiddling .conf files should never be necessary (except for on-line media)
