Liteon dvd rom help

My liteon dvd rom died on me this morning so i went and bought a new one exact same model. I put the new drive it and made sure everything was same setting as before. But im having problems, i put an original dvd in and it plays ok, i put a backup dvd in and it wont read it / i put a mp3 in and it wont read it?

I cant do on the fly copies because i keep getting read error no matter what i use. I took the drive back to the shop and they tested it everything played spot on?

So why wont it play anything i put in it apart from originals? Nothing has changed from taking the old drive out to putting the new drive in.

Its doing my head in…Anyone have any ideas?

What about the dvd backup’s that weren’t reading for you? Did you have them try that during the test?
