My BDP-1 is connected to the BDA-1, but not to a network or any PC, just to an external HDD. My question was like if I needed a media player like itunes or something else to download the HI RES and play them, but I guess I got my answer from second post, like I can just download directly from the site to my PC, copy to the external HDD, plug in BDP-1 and play it, and no need for additional software on my PC to organise or whatever, since I'll never play it on my PC.
