Query: Warning - doesn't work with DRM files

If you would like to use this device to listen to audiobooks, or basically with any DRM files, DO NOT PURCHASE!!!The company has a beta patch that supposedly lets Windows Media Player recognize the device but it does not work.I have no issues with this device for music, but the company claims that it will work with DRM files and it absolutely does not because the Windows Media Player will not recognize this device.
