I know that most people are probably already aware of the DLNA capabilities of the phone, but in case there is one or two who don't I figured I would share a cool trick. I have a 3D tv, a PS3, and an HTC Evo 3D. I loaded the 'Media Share' app that comes pre-loaded on the phone, and selected the folders on my phone which I wanted to share.
I turned on my TV and PS3. On the PS3 media crossbar, I went to Video, and searched for media servers. I then clicked on my phone, and selected the video folder. It loaded all of the videos from my phone. I started streaming "Tron: Legacy" and it was in the side by side mode. I changed the options of my 3D emitter from normal, to Left:Right, and voila. My Evo 3D was streaming 3D content to my TV.
I don't know if everyone has the capability of changing the 3D mode of their emitter, but if you do, it should work.
