Overdrive Media is a media library designed to work with Windows Media Player. It gives you the ability to view audio, video and audio book files. Most ODM files are saved in the WMA or WMV format. Some files may be protected by Digital Rights Media (DRM), making it illegal to download to other players or share the files. You can use an application called Tunebite to legally remove the DRM and convert the files to MP3. It is still illegal to share the files once you have removed the DRM; you can only remove it for personal use.
Launch your Web browser and open audials.com/en/tunebite/index.html. Click the "Download and Test Audials Tunebite 8 Now!" link. Save the file to your desktop. Double-click the download file to install it onto your computer. Wait for the installation to complete and restart your computer. Use the trial version. If you want to purchase the full version once your trial version expires, the cost as of July 2011 is $26.90.
Double-click the "Tunebite" icon to open the application. Click "Add." Double-click the ODM file that you want to convert.
Select "MP3" as the "Output" format. Highlight the ODM file that you want to convert.
Click "Record." Tunebit will remove the ODM DRM and convert it to an MP3.
