Thumbnail question

Hi, i started using serviio and i love it, it works really good but i noticed that movie metadata works fine on my ps3 and xbox but they don't show on my wdtv live hd nor my PBO, are there any settings i need to change so that movie thumbnails show on my WDTV live?
Thanks

Most likely it is not supported by those devices over DLNA. Do you see thumbnails when using other DLNA servers (specically DLNA, not Samba, or USB etc)
