Cd dvd problem

[Marmon Rule]

Hello,
I have an acer 5520 that won't read the dvd player. It gives an unreadedable error. I replaced the dvd drive and it does the same thing. Device manager says the drivers are correct and it is operating fine. Help

Bad DVD media?

Not media. Tried music and data discs.
