Instructions
Preparing the Wii
Download ModMii for Windows to a PC (see Resources). Once downloaded, run the ModMii.exe file.
Follow the instructions as presented to prepare the SD card. Insert the SD card and copy the folder created by ModMii in the case that the SD card was not inserted during the setup.
Download the Homebrew Browser (see Resources). Unzip the file and copy the application onto the SD card. Place the folder in the /apps/ folder created by ModMii. The /apps/ folder is where all applications that are played in Homebrew Channel should be placed.
Plug the hard drive into the PC and locate a video file. Copy the video file into an easy-to-remember location on the portable hard drive. After the transfer is finished, unplug the hard drive but do not plug it into the Wii yet.
Playing Video Files
Insert the SD card into the Wii and click on the Homebrew Channel. Select the Homebrew Browser application. Homebrew Browser is an application that presents a convenient list of software for the Wii that can be downloaded and extracted automatically.
Go to the Media Players tab and download MPlayer or WiiMC. Both players work for this task, with the most obvious difference being that WiiMC can use the Wiimote's pointing function. Once installed, run the media player software.
Plug in the portable hard drive while the media player software is running. Select the portable hard drive when it appears. Follow the appropriate folders until the video file is reached. Select the video file to play it.
