OverDrive Media Console (OMC) MediaMarkers™ are a navigational ‘value-add’ applied to all audio, video, and music content, and are most similar in functionality to a track/chapter list or a Table of Contents.You will be advised if you need to provide this additional information for your content.

Yes, if the files are converted to WMA or WMV.OverDrive WMA Audiobook, OverDrive Music (WMA), and OverDrive Video (WMV) files are protected using the Windows Media DRM digital rights management platform. Windows Media Rights Manager, a component of this platform, uses an encryption algorithm to encrypt your files and lock them with a “key”. This results in a packaged file that only the intended recipient should be able to open.
Additionally, each Windows Media Player is made unique by linking the Player to the host computer. This process reduces the likelihood that a compromised player will be widely distributed on the Internet, as a compromised player can be identified and disabled during the licensing process.
OverDrive also supports the MP3 format for audio content, allowing titles, where permitted by the supplier, to be made available DRM-free.
