You can store and play your DRM movies you've bought from iTunes with your MBL or MBL Duo with the WD2Go Pro application with an indirect method. As long as your device is authorized to play them (You do this by syncing the device with the iTunes software that you downloaded them with.), all you have to do is 1) Open the file in your WD2Go Pro app. 2) Send the file to yourself using the "Email as a link" option in the export menu. 3) Open the email and click the link. Viola! You should be watching your DRM protected movie in a few seconds. This is useful because you can store copies of all your iTunes movies on your MBL drive and watch them without having to download them to your devices local drive.
