Protip! If you have a DVD rom drive that will read pressed DVDs but not burnt ones, you can adjust some pot meters and then it won't read pressed DVDs anymore either!

FOUR, I tired FOUR IDE DVD drives today. One of them won't read anything, one will only read pressed DVDs and burned and pressed CDs, one will only read pressed DVDs and nothing else, one reads pressed CDs and nothing else.

These things are fiiiickle.

@hp That sounds to me like the actual technical development of optical drives. Pretty sure each type of media was initially only supported pressed, and then they added tolerances so burned ones would work better.
@uliwitness two of them are DVD burners themselves. THEY HAVE NO EXCUSE!
@hp Ooops, missed that. 😅 Maybe just the laser losing adjustment over the years then.
