MPlayerWii is an audio/video player. It is a native port of the MPlayer media player. It will play almost any kind of audio file but still needs improvement on video playback.

Changes:

mount/unmount the SD card and/or USB drive so you can swap them out without reloading MPlayerWii
added USB read-ahead cache
added preliminary samba network share support
fixed startup crash when a usblan or usb keyboard is attached
added network streaming cache
added video scaling with the nunchuk (use joystick to move, Z button to stretch and C to reset)
added configuration file (put in the SD root folder)
new ascii logo by sensah
