Plex is NOT officially supported on the single drive My Cloud units. The more expensive multi drive My Cloud units do support add-on programs including the My Cloud. There are at least two ways to get cover art to show via the Twonky Media Server on the My Cloud. First way, create a single JPG image file called “folder.jpg” and place that file in to the media folder on the My Cloud and Twonky should use that image file as the cover art for ALL media file in that folder. The second way to get cover art and other information to display on DLNA clients (like the Roku Media Player) is to embed the cover art and other information into certain media file’s metadata tags.
One can use free metadata tagging programs like MP3Tag and MediaMonkey to embed metadata and cover art into certain media files. The MediaMonkey program offers the capability of tagging files via data retrieved from the Internet. The Roku Media player will display, on screen, a portion of the text one enters into the media file’s “Comments” metadata field. That is particularly helpful for people to read on the TV screen so they can decide if they want to watch that media file or not.
Haven’t used the Plex channel in a while on my Roku so I don’t remember if it will even access the Twonky Media Server on the My Cloud and how it deals with metadata in media files on the Twonky Media Server. The Roku Media Player channel will (from what I remember) access the Plex Media Server’s embedded DLNA server to show content served up by the Plex server.
