Take look at the .pdf release notes. In respect of the DLNA Media Server. If I read this right then it seems that your own files can be uploaded using FTP to a Video folder, and presumably played back from the Internal HDD,
Until this becomes a public release you might want to copy some or all of the files to a usb drive and connect to one of the rear ports on the aura and install the VLC player app. VLC can see files on a usb drive and add them to the player library.
