It's a limitation you see on some content on most DLNA "servers." Most thought it would do that but you are talking about a system designed in committee down to the lowest common denominators.
Your question has been asked many times and there is no sign that a DLNA II is in the works or that makers will offer an update for this.
I'd research and try other DLNA servers.
