Dvd rom help please

Hiya i’ve been trying to find out why my Total War games are not being read by my Optiarc AD 5540a. I’ve tried a few games some work, some don’t. The ones that dont work i’ve just noticed - it says on the front of the cases “only DVD compatible”. What does this mean? Can i download somethin to fix it? Or will i need to buy an external drive? If so any suggestions?

Thanks in advance.

If you have tools like Alcohol or Incd installed, that could be a reason…
Also, try to boot up into SAFE MODE and then install the game(s).
