Q. How can I get Twonky to provide full size artwork to media-playing clients?
It may be an issue of ‘Receiver Type’ needing to be set.
I don’t have a Xbox, but I do run BubbleUPnP on Android. And Kinsky on Android and PC. And both of these show thumbnails for the various library ‘views’, and full-size artwork when playing.
So Twonky will serve thumbnails for some DLNA clients…
