I really have no idea. I should have a play tv adapter thing arriving today and I will see what I can do without resorting to the disc. Though I am pretty sure I will have little luck.
It's just that I don't want to fork out for a brand new, full price PS3 when it isn't going to be used for gaming or for Blu-rays. I already have a PS3 and Bluray player.
Would likely turn out cheaer setting up a cheap htpc. I just wanted the simplicity of the PS3, without having to much about configuring things. Sure, I'd enoy setting up the HTPC, but I know me and it would give me sleepless nights until it was running perfectly.
