So how many people have come up with blu-ray discs that worked perfect one viewing then literally stopped being readable the next? How many have had this problem and how many titles have just stopped being playable? I had two other titles that just stopped working with my Denon 1611, not playable on my LiteOn blu-ray drive and now not playable on my Samsung 4K UHD blu-ray. And today Rambo First Blood just would not play on the Samsung or the pc rom! Finances are bad enough but now I have three movies that are not readable and there is no damage to any of the discs! While Hitchhiker's is very enjoyable and push comes to shove I can go without both Hitchhikers and Flight Plan. I will however replace Rambo one way or the other. Not one of the discs that failed had any playback issues before they stopped working out of no where!
