Since you are accessing using a TV, I suspect you are accessing the DLNA Media Server.
I would use the Twonky UI (Sharing/Media Receivers) to check the Media Receiver Type and Navigation Type for your TV. Set the navigation type to ‘Advanced Media Navigation’.
Having said all that, I don’t see a ‘sort by date’ option when browing Twonky with BubbleUPnP.
Has your TV recentyl updated its firmware?
What settings are available under ‘Opties’ ?
