Well it looks like a second disc went bad on me and I am not to happy about it. I could sware I have played this title in my current player before and am in the middle of searching for my Denon password and I hope they have a firmware update for my BDP-1611-UD Denon Blu-ray! About two days ago my blu-ray disc of Flightplan would not play in my Denon blu-ray or my lite on blu-ray rom in my pc. The Denon player spins and spins and then finally says unknown disc! The first title that seems to have gone bad is Hitchhiker's Guide To The Galaxy!
