I suspect a devilish plot
I bought a Blu-Ray Player and one Blu-Ray disk (Avatar - which I have on DVD). These worked together perfectly.
So I went shopping and bought several other Blu-Ray disks. The first one of these (Hanna, which was released yesterday and I haven't seen yet) does not play. It plays for a few seconds, then stops, then plays another few seconds, then stops, etc.
So now, unless the other disks are fine and this one is faulty, I have little choice but to go out and buy a new TV and another Blu-Ray Player. How annoying.
Do I need a full HD or is HD Ready enough? Not sure I really understand the difference yet.
