I am aware that DVD and CD players are supposed to be cleaned with a commericailly available cleaning product, but do Computer DVD burners need to be cleaned also over time.
I used Nero Ultra edition to do the burning. In fact I had one copy already made which originally played well on 1st DVD player connected to television so I made a copy using "Copy CD" from Nero Ultra Edition, This copy does not play any music at all. But now, the original source disk plays on one DVd player but with terrible distortion. What could have happened.
In summary, 1st CD-R plays with great distortion
2nd CD-r(copied copy) doesn't play at all.
