My buddy's Wii has the basics: cIOS Rev14, USB support (installer from mplayer_ce page), sd card with NeoGamma, some emulators, mplayer_ce, etc. The other day an emulator crashed and outputted some text on a black screen and rebooted his Wii. Now, all the files on the SD card were deleted except for NeoGamma. I brought the sd card home, and put all the apps back on the card including mplayer_ce. Now, mplayer_ce used to play back dvd's flawlessly. I put the SAME version back on the card, and now dvd's won't play. What could be causing this?
