DLNA is sadly such a mess. I really wish it worked, I have my Windows 7 PC and I have my DLNA media server and I have a DLNA TV and I have a phone that does DLNA.
You'd think my home would be full of interconnected multimedia, but it just. never. works. Seriously, I would pay a big amount of money to someone who just made a series of DLNA products that implemented the standard in meaning not just lip service.
