My math teacher would shoot himself in the head if he saw me writing this equation. Anywho... I got an airport extreme (4th gen) and a samsung LED tv with DLNA, which is currently working really great from Serviio client on my MacBook Pro. My question is: If I buy a external hard drive and connect it to my airport extreme with USB, is it possible to run the files on the hard drive through DLNA on my TV? I don't really know how DLNA works, but I know that you need a client on your computer, so do you need a client for the hard drive/router? Or is this already installed?
