Problem with my laptop's DVD drive

[westbengal532]

Hello.
I have this laptop (Olivetti Olibook S1530) and the DVD drive works, but some DVD's get a good run andf others won't go ahead.
I tried selecting the DVD drive in the Bios but to no avail.
Does anyone know a trick to make all DVD's run properly? I am only an amateur.
Thanks a lot and best regards

If all these DVD are factory originals (not user burn), u can try a cleaner. After that, a new drive.

If some of those DVD are user burns, best luck man, is crap-shoot.
