Batman Arkham City Retail Version DVDs Not recognised

Hi,

I have a Samsung NP550P5C-S05IN Windows 8 64-bit and a Blu-Ray drive which has read all the DVDs/CDs/BDs that have been thrown at it. But when I insert the Arkham City DVDs, they are not recognised at all. I have tried running the DVDs in a different system and the DVDs work.

So neither my drive, nor the DVDs are faulty. Please suggest what I should do and whether someone has faced a similar problem or not.


Thanks in advance !
