DLNA has been around for a while, actually, although I don't know how serious folks were about supporting it until the last few years. All of OPPO's Blu-ray players support it - the BDP-83 and BDP-80's support may still be classified as "experimental" but it is there, and the BDP-93/95 also includes support for DLNA servers. I think most uPNP servers can work with these players. I would have to look around a bit to see who else offers this, but I think Panasonic's players may do it. I suspect there are others.

I'd be leery of buying a TV for this sort of feature - you may end up compromising on picture quality to get the feature you want. A box like the WD units is cheaper than a new TV and likely to be better at the desired function, although it does add another box to the equipment rack.
