To play videos using the application in the newest update for the Max Media Player software, first please update your Max Media Player files to the appropriate version by downloading the updated Max Media Player bootme.nds file from the link below. Many downloadable files available from www.codejunkies.com will be archived in .zip format. Most modern versions of Windows will allow you extract the files from these archives, but if you do not have the option to do this please visit www.winzip.com for more information about obtaining software to extract files from this type of archive.

After extracting the bootme.nds file from this archive, connect your Max Media Dock or Max Media Player 4GB HD to your PC using the provided USB cable. The unit should be recognized as an external USB drive, and may be accessed in My Computer. Drag the bootme.nds file from your PC to this drive to transfer the updated software.
Next, download the D3V encoding software form the link above. This software will be used to convert your existing video files to the right format for the DS. The setup file should also be extracted from the .zip archive similar to the previous file downloaded. Double-click on the extracted setup file to install the encoding software on your PC.
To start the encoder, go to Start menu -> All Programs -> MAX DS Video Converter -> MAX DS Video Converter. The Video Converter window will open, allowing you to choose Open, Exit, and Encode. Click on the Open button and browse for the video file you would like to convert. Highlight the desired file and click Open to import the file. The Encode button should now be selectable. Click this button to convert your video to D3V format. The newly converted file will be placed in the same location as the original, and you will know the process was completed when the status bar fills completely.
Now simply drag this file to any location in your Max Media Dock or 4GB HDD, such as the Video folder. To play this video, disconnect the unit from your PC, and insert it into the GBA port of your DS while the Max Media Player cartridge is in the DS slot. Turn on your DS, and the Max Media Player interface should load, displaying the new version information on the top screen. Locate your video file and double-tap it to play your newly converted video.
