As explained in the other thread, yes the Twonky Media Server within the My Cloud will parse some of the Metadata tags including the album art and sent that along to the DLNA client to display. And yes the Roku Media Player channel will display the Cover Art and some other metadata (the Comment tag and Title tag for example).
The following image is of a Roku 2XS using Roku Media Player that is displaying the contents of a folder located on the My Cloud containing MP4 video files which have album art and other metadata embedded into each individual file. As it indicates, the Roku Media Player displays; the album art, title, and comments metadata tags from the media file located on the My Cloud.
